Sourcefire VRT Certified Rules Update

Synopsis:
The Sourcefire VRT is aware of multiple vulnerabilities affecting
RealPlayer, Microsoft Outlook, Apple Quicktime, Yahoo Messenger and
Symantec Veritas NetBackup. New rules have been introduced to provide
coverage for exploitation attempts targeting these vulnerabilities.


Details:
Apple QuickTime RTSP Buffer Overflow CVE-2007-0015:
Apple QuickTime suffers from a programming error that may allow a
remote attacker to overflow a fixed length buffer and execute code of
their choosing on a vulnerable system. The condition is present in the
processing of rtsp uri parameters.

A rule to detect attacks targeting this vulnerability is included in
this release and is identified as SID 9823.

Apple QuickTime Security Bypass CVE-2006-4965:
It may be possible for a remote attacker to execute arbitrary code by
using a QuickTime Media Link (QTL) file. This file may contain elements
that could call on external scripts to be executed on the vulnerable
machine.

Rules to detect attacks targeting this vulnerability are included in
this release and are identified as SIDs 9428 and 9430.

Apple QuickTime HREFTrack Scripting:
Apple QuickTime is prone to a scripting attack via the use of the
HREFTrack parameter in a media file (.mov). A remote attacker could
make use of this vulnerability to perform a cross site or cross zone
scripting attack against a vulnerable machine.

A rule to detect attacks targeting this vulnerability is included in
this release and is identified as SID 9840.

Microsoft Outlook Denial of Service CVE-2006-6659:
Microsoft Outlook is prone to a Denial of Service (DoS) attack via the
Recipient ActiveX control. An attacker would need to supply a malicious
HTML file to be viewed using Microsoft Outlook.

Rules to detect attacks targeting this vulnerability are included in
this release and are identified as SIDs 9668 through 9670.

RealNetworks RealPlayer Denial of Service CVE-2006-6847:
RealPlayer is prone to a Denial of Service (DoS) when supplied with a
long argument via the ActiveX control that invokes RealPlayer in a
browser session.

Rules to detect attacks targeting this vulnerability are included in
this release and are identified as SIDs 9671 through 9673.

Symantec Veritas NetBackup Buffer Overflow CVE-2006-5822:
The Symantec Veritas NetBackup daemon suffers from a programming error
that may allow a remote attacker to overflow a fixed length buffer and
execute code of their choosing on an affected system.

A rule to detect attacks targeting this vulnerability is included in
this release and is identified as SID 9813.

Yahoo Messenger Remote Code Execution CVE-2006-6603:
Yahoo Messenger is prone to a buffer overflow condition in the ActiveX
control YMailAttach. A remote attacker may be able to execute arbitrary
code by passing excess data to the control via a crafted HTML file.

Rules to detect attacks targeting this vulnerability are included in
this release and are identified as SIDs 9783, 9784 and 9812.

The Sourcefire VRT has also made additions to the spyware-put and
backdoor rules categories as a result of ongoing research. Extensive
modifications and rule additions have also been made to the netbios
rules category.
