Mageia 8: 2023-0031 Critical: libXpm Privilege Escalation Risk

mageia
Calendar Grey February 7, 2023
Dist Mageia Esm H88
A patch for libXpm resolves security vulnerabilities related to privilege escalation and denial of service in the Mageia operating system.
libXpm incorrectly handled calling external helper binaries

Summary

libXpm incorrectly handled calling external helper binaries. If libXpm was being used by a setuid binary, a local attacker could possibly use this issue to escalate privileges. (CVE-2022-4883)
libXpm incorrectly handled certain XPM files. If a user or automated system were tricked into opening a specially crafted XPM file, a remote attacker could possibly use this issue to cause libXpm to stop responding, resulting in a denial of service. (CVE-2022-44617, CVE-2022-46285)
