Mozilla SeaMonkey 2.x < 2.4.0 Multiple Vulnerabilities

High

Synopsis

The remote host has a web browser installed that is vulnerable to multiple attack vectors.

Description

Versions of SeaMonkey earlier than 2.4.0 are potentially affected by multiple vulnerabilities :

- If an attacker could trick a user into holding down the 'Enter' key, via a malicious game, for example, a malicious application or extension could be downloaded and executed. (CVE-2011-2372, CVE-2011-3001)

- Unspecified errors exist that can be exploited to corrupt memory. No additional information is available at this time. (CVE-2011-2995, CVE-2011-2997)

- A weakness exists when handling the 'Location' header. This can be lead to response splitting attacks when visiting a vulnerable web server. The same fix has been applied to the headers 'Content-Length' and 'Content-Disposition'. (CVE-2011-3000)

- An error exists with WebGL's ANGLE library. It does not properly check for return values from the 'GrowAtomTable()' function. This vulnerability can be exploited to cause a buffer overflow by sending a series of requests. Additionally, an unspecified error exists within WebGL that can be exploited to corrupt memory. (CVE-2011-3002, CVE-2011-3003)

- There is an error within the JSSubScriptLoader that incorrectly unwraps 'XPCNativeWrappers'. By tricking a user into installing a malicious plug-in, an attacker could exploit this issue to execute arbitrary code. (CVE-2011-3004)

- A use-after-free error exists when parsing OGG headers. (CVE-2011-3005)

- There is an unspecified error within the YARR regular expression library that can be exploited to corrupt memory. (CVE-2011-3232)

Solution

Upgrade to SeaMonkey 2.4.0 or later.
