Description

This security bulletin contains information about 1 vulnerability.


1) Input validation error (CVE-ID: CVE-2011-3494)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber


The vulnerability allows remote attackers to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (crash) and possibly execute arbitrary code via (1) a long StyleTemplate element in a QUO, SUM or POR file, which triggers a stack-based buffer overflow, or (2) a long Font->FaceName field (aka FaceName element), which triggers a heap-based buffer overflow.
