>
> TITLE:
> Trend Micro Products SSAPI Module Long Path Processing Buffer
> Overflow
>
> SECUNIA ADVISORY ID:
> SA26557
>
> VERIFY ADVISORY:
> http://secunia.com/advisories/26557/
>
> CRITICAL:
> Moderately critical
>
> IMPACT:
> Privilege escalation, System access
>
> WHERE:
> From local network
>
> SOFTWARE:
> Trend Micro PC-cillin Internet Security 2007

>
> DESCRIPTION:
> A vulnerability has been reported in Trend Micro products, which can
> be exploited by malicious, local users to gain escalated privileges
> or potentially by malicious people to compromise a user's system.
>
> The vulnerability is caused due to a boundary error within the SSAPI
> module in vstlib32.dll when processing path names. This can be
> exploited to cause a stack-based buffer overflow by e.g. creating a
> file with an overly long path name.
>
> Successful exploitation allows execution of arbitrary code with
> SYSTEM privileges, but requires that the Venus Spy Trap (VST)
> functionality of SSAPI is enabled.
>
> The vulnerability affects the following products:
> * Trend Micro PC-cillin Internet Security 2007 15.0 - SSAPI version
> 5.0.0.1066

> will reportedly be available via the Trend Micro ActiveUpdate servers
> on September 10, 2007.
