Symantec, most popularly known for their Norton line of products (including Norton Systemworks, Norton Utilities, Norton Disk Doctor, Norton Antivirus, and Norton Internet Security, to name a few) is under the microscope due to a massive exploit in over 30 of their software packages (most importantly, the Norton line) that could allow a malicious hacker to inject malware or malicious code on their systems using the oh-so-popular buffer overflow.
To my knowledge, Symantec has already issued a patch to deal with the issues, and they should be available from Symantec directly, even though they have no information on the issue on the front page of their website.
