Synopsis
========

A buffer overflow in LibAST may result in execution of arbitrary code
with escalated privileges.

Background
==========

LibAST is a utility library that was originally intended to accompany
Eterm, but may be used by various other applications.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 x11-libs/libast < 0.7 >= 0.7

Description
===========

Michael Jennings discovered an exploitable buffer overflow in the
configuration engine of LibAST.

Impact
======

The vulnerability can be exploited to gain escalated privileges if the
application using LibAST is setuid/setgid and passes a specifically
crafted filename to LibAST's configuration engine.

Workaround
==========

Identify all applications linking against LibAST and verify they are
not setuid/setgid.

Resolution
==========

All users should upgrade to the latest version and run revdep-rebuild:

# emerge --sync
# emerge --ask --oneshot --verbose >=x11-libs/libast-0.7
# revdep-rebuild

Severity: High
Title: Paros: Default administrator password
Date: January 29, 2006
Bugs: #120352
ID: 200601-15

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Synopsis
========

Paros's database component is installed without a password, allowing
execution of arbitrary system commands.

Background
==========

Paros is an intercepting proxy between a web server and a client meant
to be used for security assessments. It allows the user to watch and
modify the HTTP(S) traffic.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-proxy/paros <= 3.2.5 > 3.2.5

Description
===========

Andrew Christensen discovered that in older versions of Paros the
database component HSQLDB is installed with an empty password for the
database administrator "sa".

Impact
======

Since the database listens globally by default, an attacker can connect
and issue arbitrary commands, including execution of binaries installed
on the host.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Paros users should upgrade to the latest version:

# emerge --snyc
# emerge --ask --oneshot --verbose ">=net-proxy/paros-3.2.8"
