Windows Mediaplayer separate vulnerability?

["Lise Moorveld" <lise_moorveld () hotmail com>]

Hello,

In Microsoft Security Bulletin MS03-040 [1] regarding a cumulative patch for 
Internet Explorer, users are recommended to install a patch for Windows 
Mediaplayer (KB article 828026 [2]). However, they state that this is not a 
security issue.

CERT, on the other hand, states the following about the Mediaplayer issue in 
VU#222044 [3]:
"A remote attacker may be able to execute arbitrary code on the local 
system."
Which sounds pretty serious.

Secunia appears to agree [4]. However, it is unclear on what information 
both CERT and Secunia base this conclusion.

Finally, SecurityFocus links this issue to an issue [5] reported by 
http-equiv back in july in BID8263 [6]. Although SecurityFocus does admit 
there is very little info at the moment on which to base this.

Does anybody know what's up? Is this a new issue that is being downplayed by 
Microsoft? Is it an old issue? Or is it really not a security issue and can 
it only be exploited in conjunction with other vulnerabilities, as MS 
states.

Any ideas?

regards,

Lise
