Mozilla Patches Firefox, Thunderbird

Mozilla has pushed to users a minor upgrade to Firefox Thursday which included seven security fixes, four of which the company considered "critical." In addition to the patches, the update also included improvements to the product's stability. Of the critical updates, a RSA signature forgery flaw, a memory corruption vulnerability, and two JavaScript issues were remedied.

Firefox 1.5.0.7 included far less critical patches than previous versions; version 1.5.0.5, released in July, included seven critical fixes and 12 altogether. In addition to Firefox, Mozilla on Friday released Thunderbird 1.5.0.7, which also fixed seven security issues as well as providing improvements to product stability. Both updates will be delivered automatically to users through the company's upgrade system, it said.
