Here are the latest Security Patches and updates issued by software vendors:

Adobe Reader & Acrobat: Adobe Reader and Acrobat suffer from javaScript vulnerabilities that have been patched in version 9.1.1.

QuickTime: Apple released a security update for QuickTime that fixes 10 vulnerabilities which can allow code execution. As usual when these types of vulnerabilities are patched it is recommended that you update the software as soon as possible.

Firefox: Mozilla has updated Firefox to version 3.0.10. The new version fixes a stability issue and a security vulnerability.

Adobe has issued a Security Update for Adobe Reader and Adobe Acrobat.

If left unpatched, the vulnerability can allow a malicious user to gain access to your computer. I strongly advise that those with older versions of Adobe Reader upgrade to the latest version immediately.
