This could lead to an head-based buffer overflow. </p> </description> <impact type="normal"> <p> By enticing a user to open a specially crafted WMF file, a remote attacker could cause a heap-based buffer overflow and execute arbitrary code with the permissions of the user running the application that uses libwmf. </p> </impact> <workaround> <p> There is no known workaround for this issue. </p> </workaround> <resolution> <p> All libwmf users should upgrade to the latest version: </p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libwmf-0.2.8.4"</code> </resolution> <references> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3376">CVE-2006-3376</uri> </references> <metadata tag="requester" timestamp="2006-08-07T08:01:55Z"> falco </metadata> <metadata tag="submitter" timestamp="2006-08-07T12:39:07Z"> dizzutch </metadata> <metadata tag="bugReady" timestamp="2006-08-08T11:33:41Z"> falco </metadata> </glsa>
