CVE-2009-2175: Henning Makholm Xcftools

Medium severity, CVSS 4.3. EPSS: 3.1% chance of exploitation in the next 30 days.

Stack-based buffer overflow in the flattenIncrementally function in flatten.c in xcftools 1.0.4, as reachable from the (1) xcf2pnm and (2) xcf2png utilities, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted image that causes a conversion to a location "above or to the left of the canvas." NOTE: some of these details are obtained from third party information.
