CVE-2024-2494: Red Hat Enterprise Linux 6

Medium severity, CVSS 6.2. EPSS: 0.4% chance of exploitation in the next 30 days.

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.
