Synopsis ========
Multiple vulnerabilities have been found in libvirt, allowing remote attackers to execute arbitrary code or cause Denial of Service.
Background ==========
libvirt is a C toolkit for manipulating virtual machines.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-emulation/libvirt < 1.0.5.1-r3 >= 1.0.5.1-r3
Description ===========
An error in the virNetMessageFree() function in rpc/virnetserverclient.c can lead to a use-after-free. Additionally, a socket leak in the remoteDispatchStoragePoolListAllVolumes command can lead to file descriptor exhaustion.
Impact ======
A remote attacker could cause certain errors during an RPC connection to cause a message to be freed without being removed from the message queue, possibly resulting in execution of arbitrary code or a Denial of Service condition. Additionally, a remote attacker could repeatedly issue the command to list all pool volumes, causing a Denial of Service condition.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All libvirt users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot -v ">=app-emulation/libvirt-1.0.5.1-r3"
