| CVE-2023-1326 | 1 Canonical | 2 Apport, Ubuntu Linux | 2025-02-07 | 7.7 High |
| A privilege escalation attack was found in apport-cli 2.26.0 and earlier which is similar to CVE-2023-26604. If a system is specially configured to allow unprivileged users to run sudo apport-cli, less is configured as the pager, and the terminal size can be set: a local attacker can escalate privilege. It is extremely unlikely that a system administrator would configure sudo to allow unprivileged users to perform this class of exploit. | ||||
| CVE-2022-2084 | 1 Canonical | 2 Cloud-init, Ubuntu Linux | 2025-02-05 | 5.5 Medium |
| Sensitive data could be exposed in world readable logs of cloud-init before version 22.3 when schema failures are reported. This leak could include hashed passwords. | ||||
| CVE-2021-3429 | 2 Canonical, Redhat | 3 Cloud-init, Enterprise Linux, Rhel Eus | 2025-02-05 | 5.5 Medium |
| When instructing cloud-init to set a random password for a new user account, versions before 21.2 would write that password to the world-readable log file /var/log/cloud-init-output.log. This could allow a local user to log in as another user. | ||||
| CVE-2018-7184 | 5 Canonical, Netapp, Ntp and 2 more | 10 Ubuntu Linux, Cloud Backup, Steelstore Cloud Integrated Storage and 7 more | 2025-01-14 | N/A |
| ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the "received" timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp. This issue is a result of an incomplete fix for CVE-2015-7704. | ||||
| CVE-2019-19344 | 4 Canonical, Opensuse, Samba and 1 more | 7 Ubuntu Linux, Leap, Samba and 4 more | 2025-01-14 | 6.5 Medium |
| There is a use-after-free issue in all samba 4.9.x versions before 4.9.18, all samba 4.10.x versions before 4.10.12 and all samba 4.11.x versions before 4.11.5, essentially due to a call to realloc() while other local variables still point at the original buffer. | ||||
| CVE-2019-9518 | 11 Apache, Apple, Canonical and 8 more | 26 Traffic Server, Mac Os X, Swiftnio and 23 more | 2025-01-14 | 7.5 High |
| Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU. | ||||
| CVE-2019-9517 | 12 Apache, Apple, Canonical and 9 more | 28 Http Server, Traffic Server, Mac Os X and 25 more | 2025-01-14 | 7.5 High |
| Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both. | ||||
| CVE-2019-9516 | 12 Apache, Apple, Canonical and 9 more | 24 Traffic Server, Mac Os X, Swiftnio and 21 more | 2025-01-14 | 6.5 Medium |
| Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory. | ||||
| CVE-2019-14907 | 6 Canonical, Debian, Fedoraproject and 3 more | 10 Ubuntu Linux, Debian Linux, Fedora and 7 more | 2025-01-14 | 6.5 Medium |
| All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless). | ||||
| CVE-2018-7185 | 6 Canonical, Hpe, Netapp and 3 more | 23 Ubuntu Linux, Hpux-ntp, Hci and 20 more | 2025-01-14 | 7.5 High |
| The protocol engine in ntp 4.2.6 before 4.2.8p11 allows a remote attackers to cause a denial of service (disruption) by continually sending a packet with a zero-origin timestamp and source IP address of the "other side" of an interleaved association causing the victim ntpd to reset its association. | ||||
| CVE-2019-9515 | 12 Apache, Apple, Canonical and 9 more | 36 Traffic Server, Mac Os X, Swiftnio and 33 more | 2025-01-14 | 7.5 High |
| Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. | ||||
| CVE-2017-5753 | 14 Arm, Canonical, Debian and 11 more | 396 Cortex-a12, Cortex-a12 Firmware, Cortex-a15 and 393 more | 2025-01-14 | 5.6 Medium |
| Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. | ||||
| CVE-2019-9511 | 12 Apache, Apple, Canonical and 9 more | 29 Traffic Server, Mac Os X, Swiftnio and 26 more | 2025-01-14 | 7.5 High |
| Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. | ||||
| CVE-2019-9513 | 12 Apache, Apple, Canonical and 9 more | 25 Traffic Server, Mac Os X, Swiftnio and 22 more | 2025-01-14 | 7.5 High |
| Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU. | ||||
| CVE-2019-9514 | 13 Apache, Apple, Canonical and 10 more | 44 Traffic Server, Mac Os X, Swiftnio and 41 more | 2025-01-14 | 7.5 High |
| Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. | ||||
| CVE-2023-32549 | 1 Canonical | 1 Landscape | 2025-01-07 | 6.8 Medium |
| Landscape cryptographic keys were insecurely generated with a weak pseudo-random generator. | ||||
| CVE-2023-32550 | 1 Canonical | 1 Landscape | 2025-01-07 | 9.3 Critical |
| Landscape's server-status page exposed sensitive system information. This data leak included GET requests which contain information to attack and leak further information from the Landscape API. | ||||
| CVE-2023-32551 | 1 Canonical | 1 Landscape | 2025-01-07 | 6.1 Medium |
| Landscape allowed URLs which caused open redirection. | ||||
| CVE-2017-18017 | 9 Arista, Canonical, Debian and 6 more | 33 Eos, Ubuntu Linux, Debian Linux and 30 more | 2025-01-03 | 9.8 Critical |
| The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. | ||||
| CVE-2024-0115 | 2 Canonical, Nvidia | 3 Ubuntu Linux, Cv-cuda, Jetpack Software Development Kit | 2024-12-26 | 6.1 Medium |
| NVIDIA CV-CUDA for Ubuntu 20.04, Ubuntu 22.04, and Jetpack contains a vulnerability in Python APIs where a user may cause an uncontrolled resource consumption issue by a long running CV-CUDA Python process. A successful exploit of this vulnerability may lead to denial of service and data loss. | ||||
