Description

This security bulletin contains information about 1 security vulnerability.


1) Resource management error (CVE-ID: CVE-2014-3657)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The virDomainListPopulate function in conf/domain_conf.c in libvirt before 1.2.9 does not clean up the lock on the list of domains, which allows remote attackers to cause a denial of service (deadlock) via a NULL value in the second parameter in the virConnectListAllDomains API command.
