Title: Apple Mac OS X Java Applet HMAC Provider Handling Remote Code Execution Vulnerability
Severity: HIGH
Description:
Apple Mac OS X is prone to a vulnerability that lets attackers run arbitrary code because the software fails to properly handle Java applets containing malicious values in the Hash-based Message Authentication Code (HMAC) provider.
This issue arises because the software fails to properly handle errors and uses an uninitialized variable in the HMAC provider for generating MD5 and SHA-1 hashes.
An attacker can exploit this issue by enticing an unsuspecting user to view a specially crafted Java applet. The attacker would likely host a malicious applet on a website and entice users to visit the site.
Successful exploits will allow the attacker to execute arbitrary code in the context of the affected software. Failed exploit attempts may result in denial-of-service conditions.
This issue affects the following:
Mac OS X 10.5.5 (and prior versions)
Mac OS X Server 10.5.5 (and prior versions)
