#VU32564 Input validation error in FreeType - CVE-2014-2241

Vulnerability identifier: #VU32564

Vulnerability risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2014-2241

CWE-ID: CWE-20

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
FreeType
Universal components / Libraries / 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
