Name of the Vulnerable Software and Affected Versions libvirt (affected versions not specified)

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.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
