Gentoo Linux Security Advisory

Title: Mozilla Thunderbird: Multiple vulnerabilities (GLSA 200503-32)
Severity: normal
Exploitable: remote
Date: March 25, 2005
Bug(s): #84075
ID: 200503-32

Synopsis

Mozilla Thunderbird is vulnerable to multiple issues, including the remote execution of arbitrary code through malicious GIF images.

Background

Mozilla Thunderbird is the next-generation mail client from the Mozilla project.

Affected Packages

Package: mail-client/mozilla-thunderbird
Vulnerable: < 1.0.2
Unaffected: >= 1.0.2
Architectures: All supported architectures

Package: mail-client/mozilla-thunderbird-bin
Vulnerable: < 1.0.2
Unaffected: >= 1.0.2
Architectures: All supported architectures


Description

The following vulnerabilities were found and fixed in Mozilla Thunderbird:
  • Mark Dowd from ISS X-Force reported an exploitable heap overrun in the GIF processing of obsolete Netscape extension 2 (CAN-2005-0399)
  • Daniel de Wildt and Gael Delalleau discovered a memory overwrite in a string library (CAN-2005-0255)
  • Wind Li discovered a possible heap overflow in UTF8 to Unicode conversion (CAN-2005-0592)
  • Phil Ringnalda reported a possible way to spoof Install source with user:pass@host (CAN-2005-0590)


Impact

The GIF heap overflow could be triggered by a malicious GIF image that would end up executing arbitrary code with the rights of the user running Thunderbird. The other overflow issues, while not thought to be exploitable, would have the same impact. Furthermore, by setting up malicious websites and convincing users to follow untrusted links, attackers may leverage the spoofing issue to trick user into installing malicious extensions.

Workaround

There is no known workaround at this time.

Resolution

All Mozilla Thunderbird users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-1.0.2"
All Mozilla Thunderbird binary users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-bin-1.0.2"
