In the code reading VCD disc labels, the ISO disc label is copied into an unprotected stack buffer of fixed size. Also, there is a buffer overflow in the code that parses subtitles and prepares them for display (XSA-2004-4). Finally, xine-lib contains a heap-based overflow in the DVD sub-picture decoder (XSA-2004-5). </p> <p> (Please note that the VCD MRL issue mentioned in XSA-2004-4 was fixed with GLSA 200408-18.) </p> </description> <impact type="normal"> <p> With carefully-crafted VCDs, DVDs, MPEGs or subtitles, an attacker may cause xine-lib to execute arbitrary code with the permissions of the user. </p> </impact> <workaround> <p> There is no known workaround at this time. </p> </workaround> <resolution> <p> All xine-lib users should upgrade to the latest version: </p> <code> # emerge sync # emerge -pv ">=media-libs/xine-lib-1_rc6" # emerge ">=media-libs/xine-lib-1_rc6"</code> </resolution> <references> <uri link="http://www.securityfocus.com/archive/1/375485/2004-09-02/2004-09-08/0">BugTraq Announcement (XSA-2004-4)</uri> <uri link="http://www.securityfocus.com/archive/1/375482/2004-09-02/2004-09-08/0">BugTraq Announcement (XSA-2004-5)</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-1379">CVE-2004-1379</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-1475">CVE-2004-1475</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-1476">CVE-2004-1476</uri> </references> <metadata tag="requester" timestamp="2004-09-20T06:34:44Z"> jaervosz </metadata> <metadata tag="submitter" timestamp="2004-09-21T20:55:54Z"> jaervosz </metadata> <metadata tag="bugReady" timestamp="2004-09-22T11:19:16Z"> koon </metadata> </glsa>
