Security Bulletin

1) Input validation error
EUVDB-ID: #VU32564
Risk: Medium
CVSSv3.1: 6.4 [CVSS:3.1/CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2014-2241
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe 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.
MitigationInstall update from vendor's website.
Vulnerable software versionsFreeType: 2.5.1 - 2.5.2
