Bastien Roucaries reported that the "dvips" application is vulnerable to two stack-based buffer overflows when processing DVI documents with long \href{} URIs (CVE-2007-5935). teTeX also includes code from Xpdf that is vulnerable to a memory corruption and two heap-based buffer overflows (GLSA 200711-22); and it contains code from T1Lib that is vulnerable to a buffer overflow when processing an overly long font filename (GLSA 200710-12). </p> </description> <impact type="normal"> <p> A remote attacker could entice a user to process a specially crafted DVI or PDF file which could lead to the execution of arbitrary code with the privileges of the user running the application. A local attacker could exploit the "dvilj" vulnerability to conduct a symlink attack to overwrite arbitrary files. </p> </impact> <workaround> <p> There is no known workaround at this time. </p> </workaround> <resolution> <p> All teTeX users should upgrade to the latest version: </p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/tetex-3.0_p1-r6"</code> </resolution> <references> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5935">CVE-2007-5935</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5936">CVE-2007-5936</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5937">CVE-2007-5937</uri> <uri link="https://www.gentoo.org/security/en/glsa/glsa-200710-12.xml">GLSA 200710-12</uri> <uri link="https://www.gentoo.org/security/en/glsa/glsa-200711-22.xml">GLSA 200711-22</uri> </references> <metadata tag="submitter" timestamp="2007-11-13T01:13:42Z"> rbu </metadata> <metadata tag="bugReady" timestamp="2007-11-18T21:46:32Z"> rbu </metadata> </glsa>
