Publication date: 14 Jan 2024
Modification date: 14 Jan 2024
Type: security
Affected Mageia releases : 9
CVE: CVE-2023-6377 , CVE-2023-6478

Description

The updated packages fix security vulnerabilities:
A flaw was found in xorg-server. Querying or changing XKB button actions
such as moving from a touchpad to a mouse can result in out-of-bounds
memory reads and writes. This may allow local privilege escalation or
possible remote code execution in cases where X11 forwarding is
involved. (CVE-2023-6377)
A flaw was found in xorg-server. A specially crafted request to
RRChangeProviderProperty or RRChangeOutputProperty can trigger an
integer overflow which may lead to a disclosure of sensitive
information. (CVE-2023-6478)
