Last modified Jun 17, 2026

CVE-2015-1803 is a vulnerability of currently unknown severity. The bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 does not properly handle character bitmaps it cannot read, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and crash) and possibly execute arbitrary code via a crafted BDF font file.. EPSS estimates a 4.90% chance of exploitation in the next 30 days.
