Following the early February Firefox update comes a Mozilla Foundation security patch for its popular Thunderbird e-mail client. Download it for Windows and Mac.
The fix addresses one critical flaw that could've potentially allowed an attacker to run arbitrary code, and closed up three other holes that only posed moderate risks, according to Mozilla. One of those included addressing persistent albeit minor crashes caused by memory corruption. More substantial fixes are expected when Mozilla releases Thunderbird 3.0, due later this year.
