It was discovered that the OverlayFS implementation in the Linux kernel did not properly handle copy up operation in some conditions. A local attacker could possibly use this to gain elevated privileges. It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux kernel did not properly perform data buffer size validation in some situations. A physically proximate attacker could use this to craft a malicious USB device that when inserted, could cause a denial of service (system crash) or possibly expose sensitive information. It was discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Various other issues were also addressed.

Red Hat Security Advisory 2023-3771-01 - The VDSM service is required by a Virtualization Manager to manage the Linux hosts. VDSM manages and monitors the host's storage, memory and networks as well as virtual machine creation, other host administration tasks, statistics gathering, and log collection. Issues addressed include bypass, denial of service, and null pointer vulnerabilities.

Debian Linux Security Advisory 5436-1 - Gregor Kopf of Secfault Security GmbH discovered that HSQLDB, a Java SQL database engine, allowed the execution of spurious scripting commands in .script and .log files. Hsqldb supports a "SCRIPT" keyword which is normally used to record the commands input by the database admin to output such a script. In combination with LibreOffice, an attacker could craft an odb containing a "database/script" file which itself contained a SCRIPT command where the contents of the file could be written to a new file whose location was determined by the attacker.

Red Hat Security Advisory 2023-3741-01 - The c-ares C library defines asynchronous DNS requests and provides name resolving API. Issues addressed include a denial of service vulnerability.

Red Hat Security Advisory 2023-3711-01 - The libtiff packages contain a library of functions for manipulating Tagged Image File Format files. Issues addressed include buffer overflow, out of bounds read, out of bounds write, and use-after-free vulnerabilities.

Red Hat Security Advisory 2023-3715-01 - The libvirt library contains a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. Issues addressed include a memory leak vulnerability.

Red Hat Security Advisory 2023-3714-01 - PostgreSQL is an advanced object-relational database management system.

Red Hat Security Advisory 2023-3725-01 - The "less" utility is a text file browser that resembles "more", but allows users to move backwards in the file as well as forwards. Since "less" does not read the entire input file at startup, it also starts more quickly than ordinary text editors.
