Detailsinfo

A vulnerability was found in FreeType 2.5/2.5.1/2.5.2 (Software Library) and classified as problematic. This issue affects the function cf2_initLocalRegionBuffer/cf2_initGlobalRegionBuffer of the file cff/cf2ft.c. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is availability. The summary by CVE is:

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.

The weakness was presented 03/12/2014 by Mateusz Jurczyk (j00ru) as Re: Two stack-based issues in freetype [NOT a request] (oss-sec). The advisory is shared at openwall.com. The identification of this vulnerability is CVE-2014-2241 since 02/28/2014. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.
