Firefox, Seamonkey and Thunderbird updates address critical errors
Mozilla has released updates to Firefox, SeaMonkey and Thunderbird, including legacy versions, to address a number of critical errors in the browsers and email clients. As the projects share code, different projects can be affected by the same bugs.
For example, Mozilla has released Firefox 3.6.20 – the latest update to the last of the old style release versions of Firefox – to address five critical and two high severity flaws in the browser. According to the advisory, these include memory safety hazards which corrupt memory, dangling pointer issues in SVGTextElement.getCharNumAtPosition and the appendChild method, and privilege escalations in event handlers and when dropping a tab element into a content area.
