TITLE:
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

WHERE:
>From remote

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.
