CVE-2013-1064

Status: ModifiedMedium (4.6)—

apt-xapian-index before 0.45ubuntu2.1, 0.44ubuntu7.1, and 0.44ubuntu5.1 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, a related issue to CVE-2013-4288.

CVSS

Version: 2.0
Vector: AV:L/AC:L/Au:N/C:P/I:P/A:P
