Description

Background

The SeaMonkey project is a community effort to deliver production-quality releases of code derived from the application formerly known as the 'Mozilla Application Suite'.

Description

Tom Ferris reported a heap-based buffer overflow involving wide SVG stroke widths that affects SeaMonkey. Various researchers reported some errors in the JavaScript engine potentially leading to memory corruption. SeaMonkey also contains minor vulnerabilities involving cache collision and unsafe pop-up restrictions, filtering or CSS rendering under certain conditions. All those vulnerabilities are the same as in GLSA 200703-04 affecting Mozilla Firefox.

Impact

An attacker could entice a user to view a specially crafted web page or to read a specially crafted email that will trigger one of the vulnerabilities, possibly leading to the execution of arbitrary code. It is also possible for an attacker to spoof the address bar, steal information through cache collision, bypass the local file protection mechanism with pop-ups, or perform cross-site scripting attacks, leading to the exposure of sensitive information, such as user credentials.

Workaround

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

Resolution

Users upgrading to the following release of SeaMonkey should note that the corresponding Mozilla Firefox upgrade has been found to lose the saved passwords file in some cases. The saved passwords are encrypted and stored in the 'signons.txt' file of ~/.mozilla/ and we advise our users to save that file before performing the upgrade.

All SeaMonkey users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=www-client/seamonkey-1.1.1"

All SeaMonkey binary users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=www-client/seamonkey-bin-1.1.1"
