Security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team discovered a series critically rated of use-after-free, out of bounds read, and buffer overflow issues using the Address Sanitizer tool in shipped software. These issues are potentially exploitable, allowing for remote code execution. We would also like to thank Abhishek for reporting three additional user-after-free and out of bounds read flaws introduced during Firefox development that were fixed before general release. In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products. The following issues were fixed in Firefox 18, ESR 17.0.1, and ESR 10.0.12: Heap-use-after-free in imgRequest::OnStopFrame (CVE-2013-0762) Heap-use-after-free in ~nsHTMLEditRules (CVE-2013-0766) Out of bounds read in nsSVGPathElement::GetPathLengthScale (CVE-2013-0767) External Reference: http://www.mozilla.org/security/announce/2013/mfsa2013-02.html Acknowledgements: Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges Abhishek Arya as the original reporter.
