Description

An issue was discovered in Exempi before 2.4.3. The VPXChunk class in XMPFiles/source/FormatSupport/WEBP_Support.cpp does not ensure nonzero widths and heights, which allows remote attackers to cause a denial of service (assertion failure and application exit) via a crafted .webp file.

Statement

This issue did not affect the versions of Exempi as shipped with Red Hat Enterprise Linux 6 and 7 as they did not include support for Web/P images.
