The first boundary error comes from some old vulnerable GD PHP code (CVE-2006-4484). </p> </description> <impact type="normal"> <p> A remote attacker can make an application using the SDL_image library to process a specially crafted GIF file or IFF ILBM file that will trigger a buffer overflow, resulting in the execution of arbitrary code with the permissions of the application or the application crash. </p> </impact> <workaround> <p> There is no known workaround at this time. </p> </workaround> <resolution> <p> All SDL_image users should upgrade to the latest version: </p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/sdl-image-1.2.6-r1"</code> </resolution> <references> <uri link="https://secunia.com/advisories/28640/">SA28640</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-6697">CVE-2007-6697</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0544">CVE-2008-0544</uri> </references> <metadata tag="submitter" timestamp="2008-01-29T09:35:04Z"> falco </metadata> <metadata tag="bugReady" timestamp="2008-01-29T09:36:22Z"> falco </metadata> </glsa>
