The get_inter_block_h263() and get_inter_block_mpeg() functions in the same file were also reported as vulnerable. </p> </description> <impact type="normal"> <p> An attacker could exploit these vulnerabilities to execute arbitrary code by tricking a user or automated system into processing a malicious video file with an application that makes use of the Xvid library. </p> </impact> <workaround> <p> There is no known workaround at this time. </p> </workaround> <resolution> <p> All Xvid users should upgrade to the latest version: </p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/xvid-1.1.3"</code> </resolution> <references> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3329">CVE-2007-3329</uri> </references> <metadata tag="requester" timestamp="2007-07-14T21:54:33Z"> p-y </metadata> <metadata tag="submitter" timestamp="2007-07-15T18:56:27Z"> DerCorny </metadata> <metadata tag="bugReady" timestamp="2007-07-16T07:58:51Z"> p-y </metadata> </glsa>
