Description Johannes Segitz 2015-02-09 10:13:07 UTC 
CVE-2014-9656

The tt_sbit_decoder_load_image function in sfnt/ttsbit.c in FreeType before
2.5.4 does not properly check for an integer overflow, which allows remote
attackers to cause a denial of service (out-of-bounds read) or possibly have
unspecified other impact via a crafted OpenType font.

SLE11 is not affected, I have not found the code in freetype2-2.3.7 and the poc file does not crash.
