Ravens PHP Scripts - Mac OS X Java Multiple Vulnerabilities

SECUNIA ADVISORY ID: SA32018

VERIFY ADVISORY: http://secunia.com/advisories/32018/

CRITICAL: Highly critical

IMPACT: Security Bypass, Exposure of system information, Exposure of sensitive information, DoS, System access

OPERATING SYSTEM: Apple Macintosh OS X - http://secunia.com/advisories/product/96/

DESCRIPTION: Some vulnerabilities have been reported and acknowledged in Java for Mac OS X, which can be exploited by malicious people to cause a DoS (Denial of Service), to bypass certain security restrictions, disclose system information or potentially sensitive information, or to compromise a vulnerable system.

1) An error leading to the use of an uninitialized variable exists in the hash-based Message Authentication Code (HMAC) provider. This can potentially be exploited to execute arbitrary code when a user visits a web page containing a specially crafted java applet.

2) An error in the Java plug-in within the handling of "file://" URLs can be exploited to launch local files when a user visits a web page containing a specially crafted java applet. Mac OS X 10.4 is reportedly not affected.

3) Some vulnerabilities in Java 1.4.2_16 and Java 1.5.0_13 can be exploited by malicious people to cause a DoS (Denial of Service), to bypass certain security restrictions, disclose system information or potentially sensitive information, or to compromise a vulnerable system.
