CVE-2018-16323 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. ReadXBMImage in coders/xbm.c in ImageMagick before 7.0.8-9 leaves data uninitialized when processing an XBM file that has a negative pixel value. If the affected code is used as a library loaded into a process that includes sensitive information, that information sometimes can be leaked via the image data.. EPSS estimates a 49.32% chance of exploitation in the next 30 days.
