This signature detects an attempt to exploit an vulnerability in MS Office Publisher 2007 which could result in remote code execution.
Microsoft Office Publisher is an application for designing and publishing documents.
Publisher is prone to a remote code-execution vulnerability due to an invalid memory reference error when handling malformed legacy document file. The vulnerability resides in the 'PUBCONV.DLL' Publisher conversion library used by the application to convert files from previous versions to Publisher 2007.
An attacker can exploit this issue by enticing an unsuspecting victim to open a maliciously crafted Publisher file.
Successful exploits may allow attackers to execute arbitrary code with privileges of the user running the application. This may facilitate a compromise of vulnerable computers.
