CVE-2017-18235 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.09% chance of exploitation in the next 30 days.
