USN-981-1: libwww-perl vulnerability

31 August 2010




It was discovered that libwww-perl incorrectly filtered filenames suggested
by Content-Disposition headers. If a user were tricked into downloading a
file from a malicious site, a remote attacker could overwrite hidden files
in the user's directory.

Update instructions

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

Ubuntu 9.10
Ubuntu 9.04
Ubuntu 8.04
Ubuntu 6.06
Ubuntu 10.04

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