The WebGLBuffer::FindMaxUshortElement function in Mozilla Firefox 4.x through 11.0, Firefox ESR 10.x before 10.0.4, Thunderbird 5.0 through 11.0, Thunderbird ESR 10.x before 10.0.4, and SeaMonkey before 2.9 calls the FindMaxElementInSubArray function with incorrect template arguments, which allows remote attackers to obtain sensitive information from video memory via a crafted WebGL.drawElements call.
This is a vulnerability exploitable with network access which means the vulnerable software is bound to
the network stack and the attacker does not require local network access or local access to exploit it.
Such a vulnerability is often termed “remotely exploitable”.
Specialized access conditions or extenuating circumstances do not exist. The following are examples:
The affected product typically requires access to a wide range of systems and users, possibly anonymous an untrusted (e.g., Internet-facing web or mail server).
The affected configuration is default or ubiquitous. The attack can be performed manually and requires little skill or additional information gathering.
The 'race condition' is a lazy one (i.e., it is technically a race but easily winnable).
Authentication is not required to access and exploit the vulnerability.
There is considerable informational disclosure. Access to some system files is
possible, but the attacker does not have control over what is obtained, or the scope of
the loss is constrained. An example is a vulnerability that divulges only certain tables
in a database.
There is no impact to the integrity of the system.
There is no impact to the availability of the system.
