Symantec on Wednesday named more than 60 of its products as affected by the critical vulnerability disclosed earlier this week, and said it was pushing out a "heuristic detection that would spot potential exploits. However, no patches have yet been released.

The number of impacted products was among the largest ever for a single vulnerability, and demonstrated the risk of reusing code in a large group of programs.

The bug, which was made public Tuesday by researcher Alex Wheeler, is in how Symantec's AntiVirus Library, part of virtually all the Cupertino, Calif.-based security giant's programs, handles RAR compressed files. RAR files are created by the WinRAR compression utility, developed and sold by RarLab.

In an advisory released Wednesday, Symantec listed 48 enterprise titles and 15 consumer products that used the flawed Library. On the consumer side, the 2006 versions of Norton AntiVirus, Internet Security, SystemWorks, and Personal Firewall are open to attack. Corporate titles such as Norton AntiVirus for Microsoft Exchange, BrightMail Antispam, and AntiVirus for Handhelds are also on the list.
