Package : libtasn1-2
Vulnerability : buffer overflows
Problem type : remote
Debian-specific: no
CVE ID : CVE-2006-0645
Bugtraq ID : 16568

Evgeny Legerov discovered several out-of-bounds memory accesses
in the DER decoding component component of the Tiny ASN.1 Library
that allows attackers to crash the DER decoder and possibly execute
arbitrary code.

The old stable distribution (woody) is not affected by these
problems.

For the stable distribution (sarge) these problems have been
fixed in version 2_0.2.10-3sarge1.

For the unstable distribution (sid) these problems will be fixed
soon.

We recommend that you upgrade your gnutls packages.

Upgrade Instructions

dpkg -i file.deb

will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update

will update the internal database apt-get upgrade

will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.

Package : gnutls11
Vulnerability : buffer overflows
Problem type : remote
Debian-specific: no
CVE ID : CVE-2006-0645
BugTraq ID : 16568

Evgeny Legerov discovered several out-of-bounds memory accesses
in the DER decoding component component of the Tiny ASN.1 Library,
which is also present and used in GnuTLS, the GNU implementation
for Transport Layer Security (TLS) 1.0 and Secure Sockets Layer
(SSL) 3.0 protocols and which allows attackers to crash the DER
decoder and possibly execute arbitrary code.

The old stable distribution (woody) is not affected by these
problems.

For the stable distribution (sarge) these problems have been
fixed in version 1.0.16-13.2.

For the unstable distribution (sid) these problems will be fixed
soon.

We recommend that you upgrade your gnutls packages.

Gentoo Linux Security Advisory GLSA 200603-04

http://security.gentoo.org/

Severity: Normal
Title: IMAP Proxy: Format string vulnerabilities
Date: March 06, 2006
Bugs: #107679
ID: 200603-04

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"

Gentoo Linux Security Advisory GLSA 200603-05

http://security.gentoo.org/

Severity: Normal
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"
