USN-982-1: Wget vulnerability

02 September 2010

Releases

Packages

Details

It was discovered that Wget would use filenames provided by the server when
following 3xx redirects. If a user or automated system were tricked into
downloading a file from a malicious site, a remote attacker could create
the file with an arbitrary name (e.g. .wgetrc), and possibly run arbitrary
code.

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.

ATTENTION: This update changes previous behaviour by ignoring the filename
supplied by the server during redirects. To re-enable previous behaviour,
use the new --trust-server-names option.
