Mozilla Issues Critical Security Patch for Thunderbird Flaw

Mozilla released five patches for Thunderbird security vulnerabilities, including one critical buffer overflow bug affecting Windows machines.

Mozilla this week fixed a severe security problem in its open-source Thunderbird email client, which also serves as a client for news, RSS, and chat. The most critical flaw (CVE-2017-7845) is a buffer overflow bug affecting Thunderbird running on the Windows OS.

"A buffer overflow occurs when drawing and validating elements using Direct 3D 9 with the ANGLE graphics library, used for WebGL content," Mozilla wrote. "This is due to an incorrect value being passed within the library during checks and results in a potentially exploitable crash." The same bug was fixed in the Firefox browser earlier in December.

The critical patch was one of five security bugs Mozilla fixed this month. Others include two vulnerabilities rated high, one moderate, and one low. Both of the highly rated security flaws affected the RSS feed. The moderate and low bugs affected RSS and email, respectively.

The latest version of Thunderbird, 52.5.2, fixes all of the flaws. Read more details here.

Discovery vs. Patch Release time
From the discovery of this vulnerability in early December to the time the patch was released was only a matter of a couple of weeks which is a pat on the back for the provider, Mozilla. If businesses follow best practice guidelines, this critical vulnerability would have been patching during standard patching.
