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.

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

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

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"
