TITLE:
Sun Java Runtime Environment External XML Entities Security Bypass

SECUNIA ADVISORY ID:
SA28746

VERIFY ADVISORY:
http://secunia.com/advisories/28746/

CRITICAL:
Less critical

IMPACT:
Security Bypass

WHERE:
>From remote

SOFTWARE:
Sun Java JDK 1.6.x
http://secunia.com/product/14273/
Sun Java JRE 1.6.x / 6.x
http://secunia.com/product/12878/

DESCRIPTION:
Sun has acknowledged a security issue in Sun Java Runtime Environment
(JRE), which can be exploited by malicious people to bypass certain
security restrictions.

The security issue is caused due to the JRE processing external XML
entity references even though the "external general entities"
property is set to FALSE. This can be exploited to e.g. access
certain URLs or cause a DoS (Denial of Service) via malicious XML
documents.

Successful exploitation requires that malicious XML data is processed
within a trusted applet or Java Web Start application.

The security issue is reported in Sun JDK and JRE 6 Update 3 and
earlier. Sun JDK and JRE 5.0, and SDK and JRE 1.4.x and 1.3.x are
reportedly not affected.

SOLUTION:
Update to JDK or JRE 6 Update 4 or later.
http://java.sun.com/javase/downloads/index.jsp

JDK 6 Update 4 for Solaris is also available in the following
patches:
Java SE 6 update 4 (as delivered in patch 125136-05 or later)
Java SE 6 update 4 (as delivered in patch 125137-05 or later
(64bit))
Java SE 6 x86 update 4 (as delivered in patch 125138-05 or later)
Java SE 6 x86 update 4 (as delivered in patch 125139-05 or later
(64bit))
