Description

Multiple integer signedness errors in the pcf_get_encodings function in pcf/pcfread.c in FreeType before 2.5.4 allow remote attackers to cause a denial of service (integer overflow, NULL pointer dereference, and application crash) via a crafted PCF file that specifies negative values for the first column and first row.
