CVE-2024-2494
MEDIUMRed Hat Enterprise Linux 6, 7, 8, 9 - Denial of Service via Negative Length in RPC Library Deserialization
Title source: llmDescription
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.
