Description Agostino Sarubbo gentoo-dev 2013-10-25 13:16:01 UTC
From ${URL} :


Some vulnerabilities have been reported in libvirt, which can be exploited by malicious, local 
users to gain escalated privileges and by malicious users to bypass certain security restrictions.

1) Some errors related to the virt-login-shell binary can be exploited to e.g. overwrite arbitrary 
files with root privileges.

2) An error within the "virConnectDomainXMLToNative()" API can be exploited to gain access to 
otherwise restricted functionality via specially crafted XML data.

Fixed in the git repository.

Provided and/or discovered by:
1) The vendor credits Sebastian Krahmer, SUSE Security Team.
2) Reported by the vendor.
