Red Hat has released an additional security advisory and updated packages to address the Mozilla Firefox, Thunderbird, and SeaMonkey memory corruption vulnerabilities. CentOS has also released updated packages to address these vulnerabilities.
Multiple vulnerabilities in Mozilla Firefox, Thunderbird, and SeaMonkey could allow an unauthenticated, remote attacker to execute arbitrary code or cause a denial of service (DoS) condition on an affected system.
This update fixes two memory corruption errors in the browser engine that are used by the affected software. An attacker could exploit these vulnerabilities by convincing a user to visit a malicious web page that contains crafted content. Processing the web page could cause a memory corruption error, allowing the attacker to execute arbitrary code or cause a DoS condition on the affected system.
The following Mozilla products are vulnerable:
Firefox versions prior to 24.0
Firefox ESR versions prior to 17.0.9
Thunderbird versions prior to 24.0
Thunderbird ESR versions prior to 17.0.9
SeaMonkey versions prior to 2.21
These vulnerabilities cannot be exploited through email in the Thunderbird product because scripting is disabled by default; however, it may be possible to exploit the vulnerabilities in a browser-like context.
To exploit the vulnerabilities, the attacker may provide a link that directs a user to a malicious site and may use misleading language or instructions to convince the user to follow the provided link.
Administrators are advised to apply the appropriate updates. Users should verify that unsolicited links are safe to follow.
