CVE-2024-2494
Libvirt: negative g_new0 length can lead to unbounded memory allocation
Summary
Libvirt: negative g_new0 length can lead to unbounded memory allocation
Original description
The description as published by the source.
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.
