SUSE-SU-2015:0702-1 Security update for libXfont

LibXFont was updated to fix security problems. Following security issues were fixed: - CVE-2015-1802: The bdf parser reads a count for the number of properties defined in a font from the font file, and allocates arrays with entries for each property based on that count. It never checked to see if...

CVE-2015-1804

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 perform type conversion for metrics values, which allows remote authenticated users to cause a denial of service out-of-bounds memory access and possibly execute arbitrary co...
