CVE-2018-7998 (CCN-140197)

Assigned:2018-03-09
Published:2018-03-09
Updated:2018-03-27
Summary: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.
