Detailsinfo

A vulnerability was found in Mozilla Firefox and Thunderbird (Web Browser). It has been classified as critical. This affects an unknown code block. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 37.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The weakness was shared 03/31/2015 by Christian Holler, Andrew McCreight, Gary Kwong, Karl Tomlinson, Randell Jesup, Shu-yu Guo, Steve Fink and Tooru Fujisawa with Dell as MFSA 2015-30 as confirmed security advisory (Website). It is possible to read the advisory at mozilla.org. This vulnerability is uniquely identified as CVE-2015-0814 since 01/07/2015. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available. The advisory points out:

Mozilla developers and community identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code.
