Two Gentoo Security Advisories:
1. GLSA 200504-16 - CVS: Multiple vulnerabilities
2. GLSA 200504-17 - XV: Multiple Vulnerabilities
Detail
======
1. Alen Zukich has discovered several serious security issues in CVS,
including at least one buffer overflow (CAN-2005-0753), memory leaks
and a NULL pointer dereferencing error.
2. Greg Roelofs has reported multiple input validation errors in XV image
decoders. Tavis Ormandy of the Gentoo Linux Security Audit Team has
reported insufficient validation in the PDS (Planetary Data System)
image decoder, format string vulnerabilities in the TIFF and PDS
decoders, and insufficient protection from shell meta-characters in
malformed filenames.

Synopsis
========
Several serious vulnerabilities have been found in CVS, which may allow
an attacker to remotely compromise a CVS server or cause a DoS.
Background
==========
CVS (Concurrent Versions System) is an open-source network-transparent
version control system. It contains both a client utility and a server.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-util/cvs < 1.11.18-r1 >= 1.11.18-r1
Description
===========
Alen Zukich has discovered several serious security issues in CVS,
including at least one buffer overflow (CAN-2005-0753), memory leaks
and a NULL pointer dereferencing error.
Impact
======
An attacker could exploit these vulnerabilities to cause a Denial of
Service or execute arbitrary code with the permissions of the CVS
pserver or the authenticated user (depending on the connection method
used).
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All CVS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-util/cvs-1.11.18-r1"

Title: XV: Multiple vulnerabilities
Date: April 19, 2005
Bugs: #88742
ID: 200504-17
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Multiple vulnerabilities have been discovered in XV, potentially
resulting in the execution of arbitrary code.
Background
==========
XV is an interactive image manipulation program for the X Window
System.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/xv < 3.10a-r11 >= 3.10a-r11
Description
===========
Greg Roelofs has reported multiple input validation errors in XV image
decoders. Tavis Ormandy of the Gentoo Linux Security Audit Team has
reported insufficient validation in the PDS (Planetary Data System)
image decoder, format string vulnerabilities in the TIFF and PDS
decoders, and insufficient protection from shell meta-characters in
malformed filenames.
Impact
======
Successful exploitation would require a victim to view a specially
created image file using XV, potentially resulting in the execution of
arbitrary code.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All XV users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/xv-3.10a-r11"
