Heap-based buffer overflow in the readgifimage function in the gif2tiff tool in libtiff 4.0.3 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted height and width values in a GIF image.

Security readout for executives and security teams

CVE-2013-4243 is a memory corruption flaw in libtiff's gif2tiff converter. A specially crafted GIF with malicious dimensions can crash the tool and may allow code execution. Risk is highest where servers automatically convert untrusted GIF uploads using libtiff 4.0.3 or earlier. Exposure is most likely in systems with old libtiff packages that run gif2tiff against user-supplied GIF files, especially upload pipelines, document conversion services, and batch media processing jobs. General libtiff presence alone is not enough unless gif2tiff or the vulnerable code path is used. Prioritize remediation where image conversion is exposed to users or partners. Legacy internal-only systems are lower urgency, but unsupported libtiff versions should still be removed because the flaw can crash processing and may permit code execution. Mitigation focus: Upgrade libtiff beyond 4.0.3 using vendor-supported packages.; Apply applicable Debian, Red Hat, Gentoo, or platform vendor advisories.; Disable or isolate gif2tiff processing for untrusted GIF files until patched..
