Four Gentoo Linux Security Advisories:
1. GLSA 200505-15 - gdb
2. GLSA 200505-16 - mageMagick, GraphicsMagick:
3. GLSA 200505-13:02 - FreeRADIUS: SQL injection
4. GLSA 200504-23:02 - Kommander
Detail
======
1. Tavis Ormandy of the Gentoo Linux Security Audit Team discovered an
integer overflow in the BFD library, resulting in a heap overflow. A
review also showed that by default, gdb insecurely sources
initialisation files from the working directory.
2. Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a
Denial of Service vulnerability in the XWD decoder of ImageMagick and
GraphicsMagick when setting a color mask to zero.
3. Primoz Bratanic discovered that the sql_escape_func function of
FreeRADIUS may be vulnerable to a buffer overflow (BID 13541). He also
discovered that FreeRADIUS fails to sanitize user-input before using it
in a SQL query, possibly allowing SQL command injection (BID 13540).
4. The fixed ebuild proposed in the original version of this Security
Advisory did not address all the vulnerabilities.

Title: gdb: Multiple vulnerabilities
Date: May 20, 2005
Bugs: #88398, #91398, #91654
ID: 200505-15

Synopsis
========
Multiple vulnerabilities have been discovered in the GNU debugger,
potentially allowing the execution of arbitrary code.
Background
==========
gdb is the GNU project's debugger, facilitating the analysis and
debugging of applications. The BFD library provides a uniform method of
accessing a variety of object file formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-devel/gdb < 6.3-r3 >= 6.3-r3
Description
===========
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered an
integer overflow in the BFD library, resulting in a heap overflow. A
review also showed that by default, gdb insecurely sources
initialisation files from the working directory.
Impact
======
Successful exploitation would result in the execution of arbitrary code
on loading a specially crafted object file or the execution of
arbitrary commands.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All gdb users should upgrade to the latest stable version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-devel/gdb-6.3-r3"
Availability
============
This GLSA and any updates to it are available for viewing at
the Gentoo Security Website:
http://security.gentoo.org/glsa/glsa-200505-15.xml
Concerns?
=========
Security is a primary focus of Gentoo Linux and ensuring the
confidentiality and security of our users machines is of utmost
importance to us. Any security concerns should be addressed to
security@gentoo.org or alternatively, you may file a bug at
http://bugs.gentoo.org.

Title: ImageMagick, GraphicsMagick: Denial of Service
vulnerability
Date: May 21, 2005
Bugs: #90423, #90595
ID: 200505-16
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
ImageMagick and GraphicsMagick utilities can be abused to perform a
Denial of Service attack.
Background
==========
Both ImageMagick and GraphicsMagick are collection of tools to read,
write and manipulate images in many formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/imagemagick < 6.2.2.3 >= 6.2.2.3
2 media-gfx/graphicsmagick < 1.1.6-r1 >= 1.1.6-r1
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a
Denial of Service vulnerability in the XWD decoder of ImageMagick and
GraphicsMagick when setting a color mask to zero.
Impact
======
A remote attacker could submit a specially crafted image to a user or
an automated system making use of an affected utility, resulting in a
Denial of Service by consumption of CPU time.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All ImageMagick users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.2.2.3"
All GraphicsMagick users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/graphicsmagick-1.1.6-r1"

Title: FreeRADIUS: SQL injection and Denial of Service
vulnerability
Date: May 17, 2005
Updated: May 20, 2005
Bugs: #91736
ID: 200505-13:02
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Errata
======
This advisory incorrectly described FreeRADIUS versions as being
vulnerable to a remote compromise. After further verifications, it
appears to only result in potential Denial of Service. The SQL injection
issue is not affected by this. Many thanks to Nicolas Baradakis for
bringing this to our attention.
The corrected sections appear below.
Synopsis
========
The FreeRADIUS server is vulnerable to an SQL injection attack and a
buffer overflow, possibly resulting in disclosure and modification of
data and Denial of Service.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-dialup/freeradius < 1.0.2-r4 >= 1.0.2-r4
Description
===========
Primoz Bratanic discovered that the sql_escape_func function of
FreeRADIUS may be vulnerable to a buffer overflow (BID 13541). He also
discovered that FreeRADIUS fails to sanitize user-input before using it
in a SQL query, possibly allowing SQL command injection (BID 13540).
Impact
======
By supplying carefully crafted input, a malicious user could cause an
SQL injection or a buffer overflow, possibly leading to the disclosure
and the modification of sensitive data or Denial of Service by crashing
the server.
Resolution
==========
All FreeRADIUS users should upgrade to the latest available version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dialup/freeradius-1.0.2-r4"
