Details

It was discovered that Java did not correctly handle untrusted applets.
If a user were tricked into running a malicious applet, a remote attacker
could gain user privileges, or list directory contents. (CVE-2008-5347,
CVE-2008-5350)

It was discovered that Kerberos authentication and RSA public key
processing were not correctly handled in Java. A remote attacker
could exploit these flaws to cause a denial of service. (CVE-2008-5348,
CVE-2008-5349)

It was discovered that Java accepted UTF-8 encodings that might be
handled incorrectly by certain applications. A remote attacker could
bypass string filters, possible leading to other exploits. (CVE-2008-5351)

Overflows were discovered in Java JAR processing. If a user or
automated system...

bypass string filters, possible leading to other exploits. (CVE-2008-5351)

Overflows were discovered in Java JAR processing. If a user or
automated system were tricked into processing a malicious JAR file,
a remote attacker could crash the application, leading to a denial of
service. (CVE-2008-5352, CVE-2008-5354)

It was discovered that Java calendar objects were not unserialized safely.
If a user or automated system were tricked into processing a specially
crafted calendar object, a remote attacker could execute arbitrary code
with user privileges. (CVE-2008-5353)

It was discovered that the Java image handling code could lead to memory
corruption. If a user or automated system were tricked into processing
a specially crafted image, a remote attacker could crash the application,
leading to a denial of service. (CVE-2008-5358, CVE-2008-5359)

It was discovered that temporary files created by Java had predictable
names. If a user or automated system were tricked into processing a
specially crafted JAR file, a remote attacker could overwrite sensitive
information. (CVE-2008-5360)

Update instructions

After a standard system upgrade you need to restart any Java applications to effect the necessary changes.

Learn more about how to get the fixes.

The problem can be corrected by updating your system to the following package versions:
