Summary

libx11 vulnerabilities

Details

USN-6407-1 fixed several vulnerabilities in libx11. This update provides the corresponding update for Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.

Original advisory details:

Gregory James Duck discovered that libx11 incorrectly handled certain keyboard symbols. If a user were tricked into connecting to a malicious X server, a remote attacker could use this issue to cause libx11 to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2023-43785)

Yair Mizrahi discovered that libx11 incorrectly handled certain malformed XPM image files. If a user were tricked into opening a specially crafted XPM image file, a remote attacker could possibly use this issue to consume memory, leading to a denial of service. (CVE-2023-43786)
