Ubuntu 8.10 / 9.04 : openjdk-6 vulnerabilities (USN-814-1)

Ubuntu Security Notice (C) 2009-2013 Canonical, Inc. / NASL script (C) 2009-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

It was discovered that the XML HMAC signature system did not correctly
check certain lengths. If an attacker sent a truncated HMAC, it could
bypass authentication, leading to potential privilege escalation.
(CVE-2009-0217)

It was discovered that JAR bundles would appear signed if only one
element was signed. If a user were tricked into running a malicious
Java applet, a remote attacker could exploit this to gain access to
private information and potentially run untrusted code.
(CVE-2009-1896)

It was discovered that certain variables could leak information. If a
user were tricked into running a malicious Java applet, a remote
attacker could exploit this to gain access to private information and
potentially run untrusted code. (CVE-2009-2475, CVE-2009-2690)

A flaw was discovered the OpenType checking. If a user were tricked
into running a malicious Java applet, a remote attacker could bypass
access restrictions. (CVE-2009-2476)

It was discovered that the XML processor did not correctly check
recursion. If a user or automated system were tricked into processing
a specially crafted XML, the system could crash, leading to a denial
of service. (CVE-2009-2625)

It was discovered that the Java audio subsystem did not correctly
validate certain parameters. If a user were tricked into running an
untrusted applet, a remote attacker could read system properties.
(CVE-2009-2670)

Multiple flaws were discovered in the proxy subsystem. If a user were
tricked into running an untrusted applet, a remote attacker could
discover local user names, obtain access to sensitive information, or
bypass socket restrictions, leading to a loss of privacy.
(CVE-2009-2671, CVE-2009-2672, CVE-2009-2673)

Flaws were discovered in the handling of JPEG images, Unpack200
archives, and JDK13Services. If a user were tricked into running an
untrusted applet, a remote attacker could load a specially crafted
file that would bypass local file access protections and run arbitrary
code with user privileges. (CVE-2009-2674, CVE-2009-2675,
CVE-2009-2676, CVE-2009-2689).

Solution :

Update the affected packages.
