The remote Fedora host is missing a security update.


A security vulnerability is found on WEBrick module in Ruby currently shipped on Fedora 12 that WEBrick lets attackers to inject malicious escape sequences to its logs, making it possible for dangerous control characters to be executed on a victim's terminal emulator. This issue has now been tagged as CVE-2009-4492. Also currently have_library() function in mkmf.rb always requires ruby's static archive to function correctly despite that ruby shared library is also provided. This new rpm will fix these issues.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected ruby package.
