Gentoo Linux Security Advisory

Title: SeaMonkey: Multiple vulnerabilities (GLSA 200701-04)
Severity: high
Exploitable: remote
Date: January 10, 2007
Bug(s): #158576
ID: 200701-04

Synopsis

Multiple vulnerabilities have been reported in the SeaMonkey project, some of which may allow the remote execution of arbitrary code.

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'.

Affected Packages

Package: www-client/seamonkey
Vulnerable: < 1.0.7
Unaffected: >= 1.0.7
Architectures: All supported architectures


Description

An anonymous researcher found evidence of memory corruption in the way SeaMonkey handles certain types of SVG comment DOM nodes. Georgi Guninski and David Bienvenu discovered buffer overflows in the processing of long "Content-Type:" and long non-ASCII MIME email headers. Additionally, Frederik Reiss discovered a heap-based buffer overflow in the conversion of a CSS cursor. Several other issues with memory corruption were also fixed. SeaMonkey also contains less severe vulnerabilities involving JavaScript and Java.

Impact

An attacker could entice a user to load malicious JavaScript or a malicious web page with a SeaMonkey application, possibly leading to the execution of arbitrary code with the rights of the user running those products. An attacker could also perform cross-site scripting attacks, leading to the exposure of sensitive information, like user credentials. Note that the execution of JavaScript or Java applets is disabled by default in the SeaMonkey email client, and enabling it is strongly discouraged.

Workaround

There are no known workarounds for all the issues at this time.

Resolution

All SeaMonkey users should upgrade to the latest version:
