The virSecurityManagerGetPrivateData function in security/security_manager.c in libvirt 0.8.8 through 0.9.1 uses the wrong argument for a sizeof call, which causes incorrect processing of "security manager private data" that "reopens disk probing" and might allow guest OS users to read arbitrary files on the host OS. NOTE: this vulnerability exists because of a CVE-2010-2238 regression.

CVE-2011-1486 [MEDIUM] libvirt vulnerabilities
Title: libvirt vulnerabilities
Summary: Libvirt could be made to crash or read arbitrary files on the host.
It was discovered that libvirt did not use thread-safe error reporting. A
remote attacker could exploit this to cause a denial of service via
application crash. (CVE-2011-1486)
Eric Blake discovered that libvirt had an off-by-one error which could
be used to reopen disk probing and bypass the fix for CVE-2010-2238. A
privileged attacker in the guest could exploit this to read arbitrary files
on the host. This issue only affected Ubuntu 11.04. By default, guests are
confined by an AppArmor profile which provided partial protection against
this flaw. (CVE-2011-2178)
Instructions: In general, a standard system update will make all the necessary changes.
