USN-953-1: fastjar vulnerability

Releases

• Ubuntu 10.04
• Ubuntu 9.10
• Ubuntu 9.04
• Ubuntu 8.04

Packages

• fastjar -

Details

Dan Rosenberg discovered that fastjar incorrectly handled file paths
containing ".." when unpacking archives. If a user or an automated system
were tricked into unpacking a specially crafted jar file, arbitrary files
could be overwritten with user privileges.

Update instructions

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

Ubuntu 9.10

• fastjar - 2:0.98-1ubuntu0.9.10.1

Ubuntu 9.04

• fastjar - 2:0.97-3ubuntu0.1

Ubuntu 8.04

• fastjar - 2:0.95-1ubuntu2.1

Ubuntu 10.04

• fastjar - 2:0.98-1ubuntu0.10.04.1

In general, a standard system update will make all the necessary changes.
