Web Attack: Microsoft Office CVE-2013-1331 3

Severity: High

This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.

Description

This signature detects attempts to exploit a buffer overflow vulnerability in Microsoft Office.

Additional Information

Microsoft Office is prone to a remote buffer-overflow vulnerability because the software fails to perform adequate boundary checks on user-supplied data. Specifically, this issue occurs when the application processes crafted PNG files.

An attacker can exploit this issue by enticing an unsuspecting user to open a malicious PNG file.

Successfully exploiting this issue would allow the attacker to corrupt memory and execute arbitrary code in the context of the currently logged-in user.
