Integer overflow in the gdImageWebpCtx function in gd_webp.c in the GD Graphics Library (aka libgd) through 2.2.3, as used in PHP through 7.0.11, allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted imagewebp and imagedestroy calls.

Security readout for executives and security teams

This flaw affects GD/libgd WebP image handling, including PHP builds using affected GD code. A remote user may be able to crash an image-processing workflow and possibly trigger other memory-corruption effects if an application exposes the vulnerable imagewebp/imagedestroy path to untrusted input. Exposure is most likely in legacy PHP or libgd deployments that generate WebP images with GD and allow attacker-influenced image processing. Systems not using GD WebP output are less likely exposed based on the supplied description. Treat as a legacy image-processing risk. Prioritize remediation where public-facing upload or conversion services still run old PHP/libgd stacks, especially if availability matters or shared hosting is involved. Mitigation focus: Inventory PHP and libgd versions on systems handling images.; Upgrade affected libgd and PHP packages using vendor guidance.; Review Debian DSA-3693 and Gentoo GLSA-201612-09 for distribution fixes..
