This may lead to a buffer overflow. </p> </description> <impact type="normal"> <p> By creating a specially crafted compressed data stream, attackers can overwrite data structures for applications that use Qt, resulting in a Denial of Service or potentially arbitrary code execution. </p> </impact> <workaround> <p> Emerge Qt with the zlib USE-flag enabled. </p> </workaround> <resolution> <p> All Qt users should upgrade to the latest version: </p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=x11-libs/qt-3.3.4-r8"</code> </resolution> <references> <uri link="https://www.gentoo.org/security/en/glsa/glsa-200507-05.xml">GLSA 200507-05</uri> <uri link="https://www.gentoo.org/security/en/glsa/glsa-200507-19.xml">GLSA 200507-19</uri> <uri link="https://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1849">CAN-2005-1849</uri> <uri link="https://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2096">CAN-2005-2096</uri> </references> <metadata tag="submitter" timestamp="2005-09-22T16:49:17Z"> jaervosz </metadata> <metadata tag="bugReady" timestamp="2005-09-23T12:32:05Z"> koon </metadata> </glsa>
