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'.
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.
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"
