Today is Microsoft Patch Tuesday for July 2005.

One of the bulletins is:

Which fails to indicate which graphics formats are affected by this
vulnerability.  It does mention that abuse thereof is indeed in the
wild.  Presumably on websites, but if you want to make sure that it is
not happening in email, you will want to remove these optimizations from
your Declude virus.cfg file:

SKIPEXT         JPG
SKIPEXT         JPEG
SKIPEXT         PNG
SKIPEXT         TIF
SKIPEXT         TIFF

This contradicts my posting in May 2005 that Scott Perry said that JPG
skipping was ok vis a vis MS04-028 Q833987 because Declude Virus checks
for corrupt JPG regardless of the SKIPEXT behaviour.  That is, unless
the Declude code is so good that it checks all three of these formats
for rigorous adherence to their standards such that it protects the
Microsoft libraries!
