Five Gentoo Linux Security Advisories:
1. GLSA 200502-14 - mod_python: Publisher Handler vulnerability
2. GLSA 200502-15 - PowerDNS: Denial of Service vulnerability
3. GLSA 200502-16 - ht://Dig: Cross-site scripting vulnerability
4. GLSA 200502-17 - Opera: Multiple vulnerabilities
5. GLSA 200502-19 - PostgreSQL: Buffer overflows in PL/PgSQL parser
Detail
======
1. Graham Dumpleton discovered a vulnerability in mod_python's Publisher
Handler.
2. A vulnerability has been reported in the DNSPacket::expand method of
dnspacket.cc.
3. Michael Krax discovered that ht://Dig fails to validate the 'config'
parameter before displaying an error message containing the parameter.
This flaw could allow an attacker to conduct cross-site scripting attacks.
4. Opera contains several vulnerabilities:
* fails to properly validate Content-Type and filename.
* fails to properly validate date: URIs.
* uses kfmclient exec as the Default Application to handle downloaded
files when integrated with KDE.
* fails to properly control frames.
* uses Sun Java packages insecurely.
* searches an insecure path for plugins.
5. PostgreSQL is vulnerable to several buffer overflows in the PL/PgSQL parser.

ID: 200502-14
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
mod_python contains a vulnerability in the Publisher Handler potentially
leading to information disclosure.
Background
==========
mod_python is an Apache module that embeds the Python interpreter within
the server allowing Python-based web-applications to be created.
Affected packages
=================
-------------------------------------------------------------------

===========
Graham Dumpleton discovered a vulnerability in mod_python's Publisher
Handler.
Impact
======
By requesting a specially crafted URL for a published module page, an
attacker could obtain information about restricted variables.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All mod_python users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-python/mod_python-3.1.3-r1"

Title: ht://Dig: Cross-site scripting vulnerability
Date: February 13, 2005
Bugs: #80602
ID: 200502-16
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
ht://Dig is vulnerable to cross-site scripting attacks.
Background
==========
ht://Dig is an HTTP/HTML indexing and searching system.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-misc/htdig < 3.1.6-r7 >= 3.1.6-r7
Description
===========
Michael Krax discovered that ht://Dig fails to validate the 'config'
parameter before displaying an error message containing the parameter.
This flaw could allow an attacker to conduct cross-site scripting attacks.
Impact
======
By sending a carefully crafted message, an attacker can inject and
execute script code in the victim's browser window. This allows to
modify the behaviour of ht://Dig, and/or leak session information such
as cookies to the attacker.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All ht://Dig users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-misc/htdig-3.1.6-r7"
