Apple Mac OS X VNC viewer weak security
|macos-vncviewer-weak-security (45174)||Low Risk|
Apple Mac OS X could provide weaker than expected security. The VNC viewer password field displays more than the maximum eight characters, making it appear as though the additional characters are used in the password. A remote attacker could exploit this vulnerability to launch further attacks on the system.
Apply Apple Security Update 2008-004 or upgrade to the latest version of Mac OS X (10.5.5 or later), available from the Apple Web site. See References.
