Gentoo - Two Security Advisories:
1. Ethereal: Multiple vulnerabilities in protocol dissectors [GLSA 200510-25]
2. XLI, Xloadimage: Buffer overflow [GLSA 200510-26]
Detail
======
Security advisory summaries:
1. Ethereal is vulnerable to numerous vulnerabilities, potentially
resulting in the execution of arbitrary code or abnormal termination.
2. When XLI or Xloadimage process an image, they create a new image object
to contain the new image, copying the title from the old image to the
newly created image. Ariel Berkman reported that the 'zoom', 'reduce',
and 'rotate' functions use a fixed length buffer to contain the new
title, which could be overwritten by the NIFF or XPM image processors.

Synopsis
========
Ethereal is vulnerable to numerous vulnerabilities, potentially
resulting in the execution of arbitrary code or abnormal termination.
Background
==========
Ethereal is a feature-rich network protocol analyzer.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-analyzer/ethereal < 0.10.13-r1 >= 0.10.13-r1
Description
===========
There are numerous vulnerabilities in versions of Ethereal prior to
0.10.13, including:
* The SLIM3 and AgentX dissectors could overflow a buffer
(CVE-2005-3243).
* iDEFENSE discovered a buffer overflow in the SRVLOC dissector
(CVE-2005-3184).
* Multiple potential crashes in many dissectors have been fixed, see
References for further details.
Furthermore an infinite loop was discovered in the IRC protocol
dissector of the 0.10.13 release (CVE-2005-3313).
Impact
======
An attacker might be able to use these vulnerabilities to crash
Ethereal or execute arbitrary code with the permissions of the user
running Ethereal, which could be the root user.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Ethereal users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.13-r1"

Title: XLI, Xloadimage: Buffer overflow
Date: October 30, 2005
Bugs: #108365
ID: 200510-26
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
XLI and Xloadimage contain a vulnerability which could potentially
result in the execution of arbitrary code.
Background
==========
XLI and Xloadimage are X11 image manipulation utilities.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/xli < 1.17.0-r2 >= 1.17.0-r2
2 media-gfx/xloadimage < 4.1-r4 >= 4.1-r4
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
When XLI or Xloadimage process an image, they create a new image object
to contain the new image, copying the title from the old image to the
newly created image. Ariel Berkman reported that the 'zoom', 'reduce',
and 'rotate' functions use a fixed length buffer to contain the new
title, which could be overwritten by the NIFF or XPM image processors.
Impact
======
A malicious user could craft a malicious XPM or NIFF file and entice a
user to view it using XLI, or manipulate it using Xloadimage,
potentially resulting in the execution of arbitrary code with the
permissions of the user running XLI or Xloadimage.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All XLI users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/xli-1.17.0-r2"
All Xloadimage users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/xloadimage-4.1-r4"
