USN-6165-1: GLib vulnerabilities It was discovered that GLib incorrectly handled non-normal GVariants. An attacker could use this issue to cause GLib to crash, resulting in a denial of service, or perform other unknown attacks. Source: USN-6165-1: GLib vulnerabilities

USN-6164-1: c-ares vulnerabilities Hannes Moesl discovered that c-ares incorrectly handled certain ipv6 addresses. An attacker could use this issue to cause c-ares to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2023-31130) Xiang Li discovered that c-ares incorrectly handled certain UDP packets. A remote attacker could possibly use this issue to cause c-res to crash, resulting in a denial of service. (CVE-2023-32067) Source: USN-6164-1: c-ares vulnerabilities

USN-6163-1: pano13 vulnerabilities It was discovered that pano13 did not properly validate the prefix provided for PTcrop’s output. An attacker could use this issue to cause pano13 to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS. (CVE-2021-20307) It was discovered that pano13 did not properly handle certain crafted TIFF images. An attacker could use this issue to cause pano13 to crash, resulting in a denial of service. (CVE-2021-33293) Source: USN-6163-1: pano13 vulnerabilities

USN-6162-1: Linux kernel (Intel IoTG) vulnerabilities Patryk Sondej and Piotr Krysiuk discovered that a race condition existed in the netfilter subsystem of the Linux kernel when processing batch requests, 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. (CVE-2023-32233) Gwangun Jung discovered that the Quick Fair Queueing scheduler implementation in the Linux kernel contained an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-31436) Reima Ishii discovered that the nested KVM implementation for Intel x86 processors in the Linux kernel did not properly validate control registers in certain situations. An attacker in a guest VM could use this to cause a denial of service (guest crash). (CVE-2023-30456) It was discovered that [ more… ]
