CVE-2024-12243 | 1 Redhat | 4 Discovery, Enterprise Linux, Openshift and 1 more | 2025-06-02 | 5.3 Medium |
A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially crafted certificate, causing GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition. | ||||
CVE-2024-12133 | 1 Redhat | 4 Discovery, Enterprise Linux, Openshift and 1 more | 2025-06-02 | 5.3 Medium |
A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate, causing a denial of service attack. | ||||
CVE-2024-0567 | 5 Debian, Fedoraproject, Gnu and 2 more | 9 Debian Linux, Fedora, Gnutls and 6 more | 2025-06-02 | 7.5 High |
A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack. | ||||
CVE-2024-2905 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhel Eus | 2025-05-29 | 6.2 Medium |
A security vulnerability has been discovered within rpm-ostree, pertaining to the /etc/shadow file in default builds having the world-readable bit enabled. This issue arises from the default permissions being set at a higher level than recommended, potentially exposing sensitive authentication data to unauthorized access. | ||||
CVE-2022-2995 | 2 Kubernetes, Redhat | 2 Cri-o, Openshift | 2025-05-29 | 7.1 High |
Incorrect handling of the supplementary groups in the CRI-O container engine might lead to sensitive information disclosure or possible data modification if an attacker has direct access to the affected container where supplementary groups are used to set access permissions and is able to execute a binary code in that container. | ||||
CVE-2025-1118 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-05-29 | 4.4 Medium |
A flaw was found in grub2. Grub's dump command is not blocked when grub is in lockdown mode, which allows the user to read any memory information, and an attacker may leverage this in order to extract signatures, salts, and other sensitive information from the memory. | ||||
CVE-2025-0677 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-05-29 | 6.4 Medium |
A flaw was found in grub2. When performing a symlink lookup, the grub's UFS module checks the inode's data size to allocate the internal buffer to read the file content, however, it fails to check if the symlink data size has overflown. When this occurs, grub_malloc() may be called with a smaller value than needed. When further reading the data from the disk into the buffer, the grub_ufs_lookup_symlink() function will write past the end of the allocated size. An attack can leverage this by crafting a malicious filesystem, and as a result, it will corrupt data stored in the heap, allowing for arbitrary code execution used to by-pass secure boot mechanisms. | ||||
CVE-2025-0622 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-05-29 | 6.4 Medium |
A flaw was found in command/gpg. In some scenarios, hooks created by loaded modules are not removed when the related module is unloaded. This flaw allows an attacker to force grub2 to call the hooks once the module that registered it was unloaded, leading to a use-after-free vulnerability. If correctly exploited, this vulnerability may result in arbitrary code execution, eventually allowing the attacker to bypass secure boot protections. | ||||
CVE-2025-26466 | 4 Canonical, Debian, Openbsd and 1 more | 5 Ubuntu Linux, Debian Linux, Openssh and 2 more | 2025-05-27 | 5.9 Medium |
A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack. | ||||
CVE-2025-4382 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-05-26 | 5.9 Medium |
A flaw was found in systems utilizing LUKS-encrypted disks with GRUB configured for TPM-based auto-decryption. When GRUB is set to automatically decrypt disks using keys stored in the TPM, it reads the decryption key into system memory. If an attacker with physical access can corrupt the underlying filesystem superblock, GRUB will fail to locate a valid filesystem and enter rescue mode. At this point, the disk is already decrypted, and the decryption key remains loaded in system memory. This scenario may allow an attacker with physical access to access the unencrypted data without any further authentication, thereby compromising data confidentiality. Furthermore, the ability to force this state through filesystem corruption also presents a data integrity concern. | ||||
CVE-2024-45776 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-05-26 | 6.7 Medium |
When reading the language .mo file in grub_mofile_open(), grub2 fails to verify an integer overflow when allocating its internal buffer. A crafted .mo file may lead the buffer size calculation to overflow, leading to out-of-bound reads and writes. This flaw allows an attacker to leak sensitive data or overwrite critical data, possibly circumventing secure boot protections. | ||||
CVE-2021-43859 | 6 Debian, Fedoraproject, Jenkins and 3 more | 14 Debian Linux, Fedora, Jenkins and 11 more | 2025-05-23 | 7.5 High |
XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible. Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not possible. | ||||
CVE-2022-41966 | 2 Redhat, Xstream | 10 Camel Quarkus, Camel Spring Boot, Jboss Enterprise Bpms Platform and 7 more | 2025-05-23 | 8.2 High |
XStream serializes Java objects to XML and back again. Versions prior to 1.4.20 may allow a remote attacker to terminate the application with a stack overflow error, resulting in a denial of service only via manipulation the processed input stream. The attack uses the hash code implementation for collections and maps to force recursive hash calculation causing a stack overflow. This issue is patched in version 1.4.20 which handles the stack overflow and raises an InputManipulationException instead. A potential workaround for users who only use HashMap or HashSet and whose XML refers these only as default map or set, is to change the default implementation of java.util.Map and java.util per the code example in the referenced advisory. However, this implies that your application does not care about the implementation of the map and all elements are comparable. | ||||
CVE-2023-48795 | 42 9bis, Apache, Apple and 39 more | 77 Kitty, Sshd, Sshj and 74 more | 2025-05-23 | 5.9 Medium |
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in [email protected] and (if CBC is used) the [email protected] MAC algorithms. This also affects Maverick Synergy Java SSH API before 3.1.0-SNAPSHOT, Dropbear through 2022.83, Ssh before 5.1.1 in Erlang/OTP, PuTTY before 0.80, AsyncSSH before 2.14.2, golang.org/x/crypto before 0.17.0, libssh before 0.10.6, libssh2 through 1.11.0, Thorn Tech SFTP Gateway before 3.4.6, Tera Term before 5.1, Paramiko before 3.4.0, jsch before 0.2.15, SFTPGo before 2.5.6, Netgate pfSense Plus through 23.09.1, Netgate pfSense CE through 2.7.2, HPN-SSH through 18.2.0, ProFTPD before 1.3.8b (and before 1.3.9rc2), ORYX CycloneSSH before 2.3.4, NetSarang XShell 7 before Build 0144, CrushFTP before 10.6.0, ConnectBot SSH library before 2.2.22, Apache MINA sshd through 2.11.0, sshj through 0.37.0, TinySSH through 20230101, trilead-ssh2 6401, LANCOM LCOS and LANconfig, FileZilla before 3.66.4, Nova before 11.8, PKIX-SSH before 14.4, SecureCRT before 9.4.3, Transmit5 before 5.10.4, Win32-OpenSSH before 9.5.0.0p1-Beta, WinSCP before 6.2.2, Bitvise SSH Server before 9.32, Bitvise SSH Client before 9.33, KiTTY through 0.76.1.13, the net-ssh gem 7.2.0 for Ruby, the mscdex ssh2 module before 1.15.0 for Node.js, the thrussh library before 0.35.1 for Rust, and the Russh crate before 0.40.2 for Rust. | ||||
CVE-2024-12401 | 1 Redhat | 8 Cert Manager, Connectivity Link, Cryostat and 5 more | 2025-05-23 | 4.4 Medium |
A flaw was found in the cert-manager package. This flaw allows an attacker who can modify PEM data that the cert-manager reads, for example, in a Secret resource, to use large amounts of CPU in the cert-manager controller pod to effectively create a denial-of-service (DoS) vector for the cert-manager in the cluster. | ||||
CVE-2024-6409 | 1 Redhat | 4 Enterprise Linux, Openshift, Rhel E4s and 1 more | 2025-05-22 | 7 High |
A race condition vulnerability was discovered in how signals are handled by OpenSSH's server (sshd). If a remote attacker does not authenticate within a set time period, then sshd's SIGALRM handler is called asynchronously. However, this signal handler calls various functions that are not async-signal-safe, for example, syslog(). As a consequence of a successful attack, in the worst case scenario, an attacker may be able to perform a remote code execution (RCE) as an unprivileged user running the sshd server. | ||||
CVE-2025-3416 | 1 Redhat | 5 Directory Server, Enterprise Linux, Openshift and 2 more | 2025-05-22 | 3.7 Low |
A flaw was found in OpenSSL's handling of the properties argument in certain functions. This vulnerability can allow use-after-free exploitation, which may result in undefined behavior or incorrect property parsing, leading to OpenSSL treating the input as an empty string. | ||||
CVE-2024-45783 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-05-22 | 4.4 Medium |
A flaw was found in grub2. When failing to mount an HFS+ grub, the hfsplus filesystem driver doesn't properly set an ERRNO value. This issue may lead to a NULL pointer access. | ||||
CVE-2024-45781 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-05-22 | 6.7 Medium |
A flaw was found in grub2. When reading a symbolic link's name from a UFS filesystem, grub2 fails to validate the string length taken as an input. The lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and eventually allowing an attacker to circumvent secure boot protections. | ||||
CVE-2024-12085 | 1 Redhat | 8 Enterprise Linux, Logging, Openshift and 5 more | 2025-05-22 | 7.5 High |
A flaw was found in rsync which could be triggered when rsync compares file checksums. This flaw allows an attacker to manipulate the checksum length (s2length) to cause a comparison between a checksum and uninitialized memory and leak one byte of uninitialized stack data at a time. |
