Greasemonkey fix is released
By Brian Livingston
The developers of Greasemonkey, a popular "extension" for the Firefox browser and other Mozilla Foundation software, released on July 30 a new version that corrects a serious security flaw. I warned about this risk in a brief news update on July 21, 2005.
The add-in enables users to redefine how Web sites look and behave. Unfortunately, older Greasemonkey versions, such as 0.3.4, allow hacker sites to read the names and contents of any files on users' hard disks.
According to Aaron Boodman, one of Greasemonkey's developers, the new beta version 0.5 closes the worst security holes. Other developers who've looked at the new code agree. Some glitches exist with the beta release, however. Although 0.5 makes it difficult for a rogue Web site to read the source code of a Greasemonkey script, it's not impossible, the team says.
Boodman recommends that people who don't want to watch out for these gotchas use version 0.3.5 of Greasemonkey instead. That version was released on July 19 and also eliminates the security flaws.
