CVE-2018-7998 (opens in a new tab)How to fix?
Upgrade Ubuntu:18.04 vips to version 8.4.5-1ubuntu0.1~esm1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream vips package and not the vips package as distributed by Ubuntu.
See How to fix? for Ubuntu:18.04 relevant fixed versions and status.
In libvips before 8.6.3, a NULL function pointer dereference vulnerability was found in the vips_region_generate function in region.c, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted image file. This occurs because of a race condition involving a failed delayed load and other worker threads.
