Apple has released a security update to its OS X 10.4 operating system. Some of the five patches in security update 10.4.7 address vulnerabilities that could allow a remote attacker to gain access to a compromised system, and one addresses a buffer-overflow flaw within ClamAV, a third-party antivirus application that is popular among Mac users. The other vulnerabilities involve Launchd, a flaw publicly exposed by the Mac virus InqTana.b earlier this year. Other vulnerablities involve OpenLDAP, ImageIO, and AFP. Additional information on the 10.4.7 patches can be obtained from Apple's security update site and from News.com.
