MGASA-2024-0114 - Updated libvirt packages fix security vulnerability

Publication date: 06 Apr 2024
URL: https://advisories.mageia.org/MGASA-2024-0114.html
Type: security
Affected Mageia releases: 9
CVE: CVE-2024-2494

Description:
A flaw was found in the RPC library APIs of libvirt. The RPC server
deserialization code allocates memory for arrays before the non-negative
length check is performed by the C API entry points. Passing a negative
length to the g_new0 function results in a crash due to the negative
length being treated as a huge positive number. This flaw allows a
local, unprivileged user to perform a denial of service attack by
causing the libvirt daemon to crash. (CVE-2024-2494)
