Java 1.3.1 and 1.4.2 Release 2 is now available and delivers the
following security enhancements for Mac OS X v10.4 or later:

Java
Available for: Java 1.4.2
Impact: Java is updated to version 1.4.2_09
Description: This release updates Java to version 1.4.2_09 to address
a number of issues. Further information is available in the 1.4.2_09
section of Sun's release notes at
http://java.sun.com/j2se/1.4.2/ReleaseNotes.html Credit to Sun and
Marc Schoenefeld for notifying us about these issues.

Java
CVE-ID: CAN-2005-2527
Available for: Java 1.4.2
Impact: A file race condition can lead to file corruption or the
creation of arbitrary files
Description: This is specific to the implementation of Java on Mac OS
X. Under certain conditions, Java may insecurely handle a temporary
directory. Subsequent file operations inside that directory could be
exposed to file race conditions. This update addresses the problem by
adding validation when operating in the temporary directory.

Java
CVE-ID: CAN-2005-2528
Available for: Java 1.3.1, Java 1.4.2
Impact: Insecure temporary file handling can lead to file corruption
or the creation of arbitrary files
Description: This is specific to the implementation of Java on Mac OS
X. The privileged helper used to update Java shared archives
insecurely creates temporary files, which can lead to a file race
condition. This update addresses the issue by avoiding file
operations in user-accessible locations. This issue does not affect
systems prior to Mac OS X v10.4. Credit to
kf_lists[at]digitalmunition[dot]com for reporting this issue.

Java
CVE-ID: CAN-2005-2529
Available for: Java 1.4.2
Impact: Malicious system users can gain elevated privileges
Description: This is specific to the implementation of Java on Mac OS
X. The utility used to update Java shared archives is susceptible to
a privilege escalation vulnerability from local system users. This
update addresses the issue by performing additional clean-up before
launching the utility on behalf of unprivileged users. This issue
does not affect systems prior to Mac OS X v10.4. Credit to Dino Dai
Zovi for reporting this issue.

Java
Available for: Java 1.3.1
Impact: Java is updated to version 1.3.1_16
