John Heasman and Mark Litchfield of NGSSoftware have discovered a critical
vulnerability
affecting Microsoft Exchange. The vulnerable versions include:
Microsoft Exchange Server 5.0 Service Pack 2
Microsoft Exchange Server 5.5 Service Pack 4
Microsoft Exchange 2000 Server Pack 3 with the Post-Service Pack 3 Update
Rollup of August 2004
Microsoft Exchange Server 2003 Service Pack 1 and Microsoft Exchange Server
2003 Service Pack 2
are *not* affected.
The vulnerability potentially allows execution of arbitrary code when the
Microsoft
Exchange Server Information Store processes a specially crafted email
message.
The flaw has now been addressed and patches are available from:
http://www.microsoft.com/technet/security/Bulletin/MS06-003.mspx
NGSSoftware are going to withhold details of this flaw for three months.
Full details will
be published on the 10th April 2006. This three month window will allow
system
administrators the time needed to obtain the patch before the details are
released to the
general public. This reflects NGSSoftware's approach to responsible
disclosure.
