Gentoo Linux Security Advisory

Title: Mozilla Thunderbird: Multiple vulnerabilities (GLSA 200703-18)
Severity: normal
Exploitable: remote
Date: March 18, 2007
Bug(s): #165555
ID: 200703-18

Synopsis

Multiple vulnerabilities have been reported in Mozilla Thunderbird, some of which may allow user-assisted arbitrary remote code execution.

Background

Mozilla Thunderbird is a popular open-source email client from the Mozilla Project.

Affected Packages

Package: mail-client/mozilla-thunderbird
Vulnerable: < 1.5.0.10
Unaffected: >= 1.5.0.10
Architectures: All supported architectures

Package: mail-client/mozilla-thunderbird-bin
Vulnerable: < 1.5.0.10
Unaffected: >= 1.5.0.10
Architectures: All supported architectures


Description

Georgi Guninski reported a possible integer overflow in the code handling text/enhanced or text/richtext MIME emails. Additionally, various researchers reported errors in the JavaScript engine potentially leading to memory corruption. Additionally, the binary version of Mozilla Thunderbird includes a vulnerable NSS library which contains two possible buffer overflows involving the SSLv2 protocol.

Impact

An attacker could entice a user to read a specially crafted email that could trigger one of the vulnerabilities, some of them being related to Mozilla Thunderbird's handling of JavaScript, possibly leading to the execution of arbitrary code.

Workaround

There is no known workaround at this time for all of these issues, but some of them can be avoided by disabling JavaScript. Note that the execution of JavaScript is disabled by default and enabling it is strongly discouraged.

Resolution

All Mozilla Thunderbird users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-1.5.0.10"
All Mozilla Thunderbird binary users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-bin-1.5.0.10"
