Title: KDE kimgio: PCX handling buffer overflow
Date: April 22, 2005
Bugs: #88862
ID: 200504-22
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
KDE fails to properly validate input when handling PCX images,
potentially resulting in the execution of arbitrary code.
Background
==========
KDE is a feature-rich graphical desktop environment for Linux and
Unix-like Operating Systems. kimgio is the KDE image handler provided
by kdelibs.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------

>= 3.3.2-r8
Description
===========
kimgio fails to properly validate input when handling PCX files.
Impact
======
By enticing a user to load a specially-crafted PCX image in a KDE
application, an attacker could execute arbitrary code.
Workaround
==========
There is no known workaround at this time.

Title: Rootkit Hunter: Insecure temporary file creation
Date: April 26, 2005
Bugs: #90007
ID: 200504-25
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Rootkit Hunter is vulnerable to symlink attacks, potentially allowing a
local user to overwrite arbitrary files.
Background
==========
Rootkit Hunter is a scanning tool to detect rootkits, backdoors and
local exploits on a local machine. Rootkit Hunter uses downloaded data
files to check file integrity. These files are updated via the
check_update.sh script.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-forensics/rkhunter < 1.2.3-r1 >= 1.2.3-r1
Description
===========
Sune Kloppenborg Jeppesen and Tavis Ormandy of the Gentoo Linux
Security Team have reported that the check_update.sh script and the
main rkhunter script insecurely creates several temporary files with
predictable filenames.
Impact
======
A local attacker could create symbolic links in the temporary files
directory, pointing to a valid file somewhere on the filesystem. When
rkhunter or the check_update.sh script runs, this would result in the
file being overwritten with the rights of the user running the utility,
which could be the root user.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Rootkit Hunter users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-forensics/rkhunter-1.2.3-r1"

Title: Convert-UUlib: Buffer overflow
Date: April 26, 2005
Bugs: #89501
ID: 200504-26
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
A buffer overflow has been reported in Convert-UUlib, potentially
resulting in the execution of arbitrary code.
Background
==========
Convert-UUlib provides a Perl interface to the uulib library, allowing
Perl applications to access data encoded in a variety of formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-perl/Convert-UUlib < 1.051 >= 1.051
Description
===========
A vulnerability has been reported in Convert-UUlib where a malformed
parameter can be provided by an attacker allowing a read operation to
overflow a buffer. The vendor credits Mark Martinec and Robert Lewis
with the discovery.
Impact
======
Successful exploitation would permit an attacker to run arbitrary code
with the privileges of the user running the Perl application.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Convert-UUlib users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-perl/Convert-UUlib-1.051"

Title: xine-lib: Two heap overflow vulnerabilities
Date: April 26, 2005
Bugs: #89976
ID: 200504-27
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Two vulnerabilities have been found in xine-lib which could lead to the
remote execution of arbitrary code.
Background
==========
xine-lib is a multimedia library which can be utilized to create
multimedia frontends.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/xine-lib < 1.0-r2 >= 1.0-r2
*>= 1_rc6-r2
Description
===========
Heap overflows have been found in the code handling RealMedia RTSP and
Microsoft Media Services streams over TCP (MMST).
Impact
======
By setting up a malicious server and enticing a user to use its
streaming data, a remote attacker could possibly execute arbitrary code
on the client computer with the permissions of the user running any
multimedia frontend making use of the xine-lib library.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All xine-lib users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose media-libs/xine-lib
