Exploit availability: No
Vulnerable software:
FreeType

Libraries used by multiple products
Vendor: freetype.org
Description
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The (1) cf2_initLocalRegionBuffer and (2) cf2_initGlobalRegionBuffer functions in cff/cf2ft.c in FreeType before 2.5.3 do not properly check if a subroutine exists, which allows remote attackers to cause a denial of service (assertion failure), as demonstrated by a crafted ttf file.
Mitigation
Install update from vendor's website.
Vulnerable software versions
FreeType: 2.5.1 - 2.5.2
