CVE-2023-5868 | 2 Postgresql, Redhat | 22 Postgresql, Advanced Cluster Security, Codeready Linux Builder Eus and 19 more | 2025-08-04 | 4.3 Medium |
A memory disclosure vulnerability was found in PostgreSQL that allows remote users to access sensitive information by exploiting certain aggregate function calls with 'unknown'-type arguments. Handling 'unknown'-type values from string literals without type designation can disclose bytes, potentially revealing notable and confidential information. This issue exists due to excessive data output in aggregate function calls, enabling remote users to read some portion of system memory. | ||||
CVE-2023-5379 | 1 Redhat | 11 Jboss Data Grid, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Eus and 8 more | 2025-08-04 | 7.5 High |
A flaw was found in Undertow. When an AJP request is sent that exceeds the max-header-size attribute in ajp-listener, JBoss EAP is marked in an error state by mod_cluster in httpd, causing JBoss EAP to close the TCP connection without returning an AJP response. This happens because mod_proxy_cluster marks the JBoss EAP instance as an error worker when the TCP connection is closed from the backend after sending the AJP request without receiving an AJP response, and stops forwarding. This issue could allow a malicious user could to repeatedly send requests that exceed the max-header-size, causing a Denial of Service (DoS). | ||||
CVE-2024-3567 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2025-08-04 | 5.5 Medium |
A flaw was found in QEMU. An assertion failure was present in the update_sctp_checksum() function in hw/net/net_tx_pkt.c when trying to calculate the checksum of a short-sized fragmented packet. This flaw allows a malicious guest to crash QEMU and cause a denial of service condition. | ||||
CVE-2024-52337 | 1 Redhat | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2025-08-04 | 5.5 Medium |
A log spoofing flaw was found in the Tuned package due to improper sanitization of some API arguments. This flaw allows an attacker to pass a controlled sequence of characters; newlines can be inserted into the log. Instead of the 'evil' the attacker could mimic a valid TuneD log line and trick the administrator. The quotes '' are usually used in TuneD logs citing raw user input, so there will always be the ' character ending the spoofed input, and the administrator can easily overlook this. This logged string is later used in logging and in the output of utilities, for example, `tuned-adm get_instances` or other third-party programs that use Tuned's D-Bus interface for such operations. | ||||
CVE-2024-8235 | 1 Redhat | 3 Advanced Virtualization, Enterprise Linux, Libvirt | 2025-08-04 | 6.2 Medium |
A flaw was found in libvirt. A refactor of the code fetching the list of interfaces for multiple APIs introduced a corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This corner case would lead to a NULL-pointer dereference and subsequent crash of virtinterfaced. This issue could allow clients connecting to the read-only socket to crash the virtinterfaced daemon. | ||||
CVE-2024-7409 | 1 Redhat | 4 Advanced Virtualization, Enterprise Linux, Openshift and 1 more | 2025-08-04 | N/A |
A flaw was found in the QEMU NBD Server. This vulnerability allows a denial of service (DoS) attack via improper synchronization during socket closure when a client keeps a socket open as the server is taken offline. | ||||
