Synopsis
========

Format string vulnerabilities in IMAP Proxy may lead to the execution
of arbitrary code when connected to malicious IMAP servers.

Background
==========

IMAP Proxy (also known as up-imapproxy) proxies IMAP transactions
between an IMAP client and an IMAP server.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-mail/up-imapproxy < 1.2.4 >= 1.2.4

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

Steve Kemp discovered two format string errors in IMAP Proxy.

Impact
======

A remote attacker could design a malicious IMAP server and entice
someone to connect to it using IMAP Proxy, resulting in the execution
of arbitrary code with the rights of the victim user.

Workaround
==========

Only connect to trusted IMAP servers using IMAP Proxy.

Resolution
==========

All IMAP Proxy users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-mail/up-imapproxy-1.2.4"

Title: zoo: Stack-based buffer overflow
Date: March 06, 2006
Bugs: #123782
ID: 200603-05

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

Synopsis
========

A stack-based buffer overflow in zoo may be exploited to execute
arbitrary code through malicious ZOO archives.

Background
==========

zoo is a file archiving utility for maintaining collections of files,
written by Rahul Dhesi.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-arch/zoo < 2.10-r1 >= 2.10-r1

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

Jean-Sebastien Guay-Leroux discovered a boundary error in the
fullpath() function in misc.c when processing overly long file and
directory names in ZOO archives.

Impact
======

An attacker could craft a malicious ZOO archive and entice someone to
open it using zoo. This would trigger a stack-based buffer overflow and
potentially allow execution of arbitrary code with the rights of the
victim user.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All zoo users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/zoo-2.10-r1"
