Mozilla has squashed their 27th security bug for the year on the Firefox browser. Late last night they released Firefox 22.214.171.124 that fixed two serious bugs, one of which also plagues Internet Explorer:
- Unescaped URIs passed to external programs [link]
- Privilege escalation through chrome-loaded about:blank windows [link]
Mozilla had just released Firefox 126.96.36.199 less than two-weeks ago to prevent Internet Explorer from inappropriately launching Firefox. Here is what I had previously said about the problem:
The new Firefox 188.8.131.52 fixes a critical flaw that enables a hacker to control a user’s computer. Ironically, this was done by letting the hacker launch Firefox through Internet Explorer, and then Firefox would run malicious instructions that could compromise their system.
It was recently discovered that Trillian is also affected when using the AIM portion, and it is expected that other applications are susceptible to the attack as well.
To the surprise of the Mozilla team, Firefox (prior to 184.108.40.206) was capable of doing the exact same thing that Internet Explorer was criticized for. A hacker could use Firefox to launch another application, and possibly run malicious instructions. Now there is even some speculation that the bug is not even the fault of the browser, but is actually a flaw in Windows. Man, I can’t remember the last time that no one would take responsibility for a security-related bug like this. Pretty soon they’ll probably be blaming the clock in the System tray for it. ;)
Aside from those fixes there were also a few minor patches thrown in, but nothing that is really significant. The update is available through the Firefox homepage, or by using the "Check for Updates" option located in the Help menu.
