Description
This security bulletin contains information about 1 security vulnerability.
1) Resource management error (CVE-ID: CVE-2012-3445)
The vulnerability allows a remote #AU# to perform service disruption.
The virTypedParameterArrayClear function in libvirt 0.9.13 does not properly handle virDomain* API calls with typed parameters, which might allow remote authenticated users to cause a denial of service (libvirtd crash) via an RPC command with nparams set to zero, which triggers an out-of-bounds read or a free of an invalid pointer.
Remediation
Install update from vendor's website.
