Mozilla re-patches Firefox 3.6 to fix plug-in problem

For the second time in two months, Mozilla on Friday rushed out a fix for Firefox to patch a problem with a browser update issued just days before.

Mozilla shipped Firefox 3.6.8 on Friday to patch a single security problem and deal with what Mike Beltzner, director of Firefox, called "a stability problem that affected some pages with embedded plug-ins." The company had released Firefox 3.6.7 two days earlier.

Mozilla patched one critical security bug in the newest update, according to an advisory also published Friday. "In certain circumstances, properties in the plug-in instance's parameter array could be freed prematurely, leaving a dangling pointer that the plug-in could execute, potentially calling into attacker-controlled memory," the warning read.
