CVE reference:CVE-2006-0007
CVE-2006-0033


Description:
Two vulnerabilities have been reported in Microsoft Office, which can be exploited by malicious people to compromise a user's system.

1) A boundary error in the GIF image filter (GIFIMP32.FLT) can be exploited to cause a buffer overflow via a specially crafted GIF file.

2) A boundary error in the PNG image filter (PNG32.FLT) can be exploited to cause a buffer overflow via a specially crafted PNG file.

Successful exploitation of the vulnerabilities allows execution of arbitrary code when a malicious image is opened in any application using the vulnerable image filters.
