Title: Lynx: Buffer overflow in NNTP processing
Date: October 17, 2005
Bugs: #108451
ID: 200510-15
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Lynx contains a buffer overflow that may be exploited to execute
arbitrary code.
Background
==========
Lynx is a text-mode browser for the World Wide Web. It supports
multiple URL types, including HTTP and NNTP URLs.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-client/lynx < 2.8.5-r1 >= 2.8.5-r1
Description
===========
When accessing a NNTP URL, Lynx connects to a NNTP server and retrieves
information about the available articles in the target newsgroup. Ulf
Harnhammar discovered a buffer overflow in a function that handles the
escaping of special characters.
Impact
======
An attacker could setup a malicious NNTP server and entice a user to
access it using Lynx (either by creating NNTP links on a web page or by
forcing a redirect for Lynx users). The data returned by the NNTP
server would trigger the buffer overflow and execute arbitrary code
with the rights of the user running Lynx.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Lynx users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/lynx-2.8.5-r1"

Title: phpMyAdmin: Local file inclusion vulnerability
Date: October 17, 2005
Bugs: #108939
ID: 200510-16
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
phpMyAdmin contains a local file inclusion vulnerability that may lead
to the execution of arbitrary code.
Background
==========
phpMyAdmin is a tool written in PHP intended to handle the
administration of MySQL over the web.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-db/phpmyadmin < 2.6.4_p2 >= 2.6.4_p2
Description
===========
Maksymilian Arciemowicz reported that in
libraries/grab_globals.lib.php, the $__redirect parameter was not
correctly validated. Systems running PHP in safe mode are not affected.
Impact
======
A local attacker may exploit this vulnerability by sending malicious
requests, causing the execution of arbitrary code with the rights of
the user running the web server.
Workaround
==========
Run PHP in safe mode.
Resolution
==========
All phpMyAdmin users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-db/phpmyadmin-2.6.4_p2"

Bugs: #109157
ID: 200510-17
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
AbiWord is vulnerable to an additional set of buffer overflows during
RTF import, making it vulnerable to the execution of arbitrary code.
Background
==========
AbiWord is a free and cross-platform word processing program. It allows
to import RTF files into AbiWord documents.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-office/abiword < 2.2.11 >= 2.2.11
Description
===========
Chris Evans discovered a different set of buffer overflows than the one
described in GLSA 200509-20 in the RTF import function in AbiWord.
Impact
======
An attacker could design a malicious RTF file and entice a user to
import it in AbiWord, potentially resulting in the execution of
arbitrary code with the rights of the user running AbiWord.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All AbiWord users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/abiword-2.2.11"
