Vulnerability details

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.


Affected software

freetype (Alpine package)
