CVE-2014-2241

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.

It was reported that Freetype before 2.5.3 suffers from an out-of-bounds stack-based read/write flaw in cf2_hintmap_build() in the CFF rasterizing code, which could lead to a buffer overflow (CVE-2014-2240).

It was also reported that Freetype before 2.5.3 has a denial-of-service vulnerability in the CFF rasterizing code, due to a reachable assertion (CVE-2014-2241).

These are all security issues fixed in the freetype2-devel-2.7-1.1 package on the GA media of openSUSE Tumbleweed.

This update for freetype2 fixes the following issues:

Update to 2.13.2:

• Some fields in the FT_Outline structure have been changed from signed to unsigned type, which better reflects the actual usage. It is also an additional means to protect against malformed input.
• Rare double-free crashes in the cache subsystem have been fixed.
• Excessive stack allocation in the autohinter has been fixed.
• The B/W rasterizer has received a major upkeep that results in large performance improvements. The rendering speed has increased and even doubled for very complex glyphs.
