CVE-2014-1538: Use After Free
Security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team discovered a number of use-after-free and out of bounds read issues using the Address Sanitizer tool. These issues are potentially exploitable, allowing for remote code execution.
In general these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled, but is potentially a risk in browser or browser-like contexts.
