Synopsis:
The Sourcefire VRT has learned of vulnerabilities affecting hosts using
the Microsoft Operating System and hosts using the Linux 2.6 kernel.


Details:
Microsoft Security Bulletin MS06-035
The mailslot service is used on hosts using the Microsoft Operating
System to handle messages between hosts on a domain.

An unchecked buffer in the mailslot server service may allow an
attacker to overflow a fixed length buffer and execute code of their
choosing on an affected host.

Rules to detect attempts to exploit this vulnerability are included in
this rule pack and are identified as sids 7035 through 7046.

Microsoft Security Bulletin MS06-037
An Excel file containing a chart object and another additional object
of any type with a large header length value, can be used to overflow a
fixed length buffer and execute code of the attackers choosing on an
affected host.

Rules to detect attempts to exploit this vulnerability are included in
this rule pack and are identified as sids 7047 and 7048.

Linux hosts using the Netfilter module may be subject to a Denial of
Service (DoS) condition when trying to process SCTP packets that do not
contain chunks.

A rule to detect attempts to exploit this vulnerability is included in
this rule pack and is identified as sid 7021.
