USN-6149-1: Linux kernel 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 the Broadcom [ more… ]

USN-6147-1: SpiderMonkey vulnerability Several security issues were discovered in the SpiderMonkey JavaScript library. If a user were tricked into opening malicious JavaScript applications or processing malformed data, a remote attacker could exploit a variety of issues related to JavaScript security, including denial of service attacks, and arbitrary code execution.

USN-6146-1: Netatalk vulnerabilities It was discovered that Netatalk did not properly validate the length of user-supplied data in the DSI structures. A remote attacker could possibly use this issue to execute arbitrary code with the privileges of the user invoking the programs. This issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2021-31439) It was discovered that Netatalk did not properly validate the length of user-supplied data in the ad_addcomment function. A remote attacker could possibly use this issue to execute arbitrary code with root privileges. This issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2022-0194) It was discovered that Netatalk did not properly handle errors when parsing AppleDouble entries. A remote attacker could possibly use this issue to execute arbitrary code with root privileges. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 [ more… ]
