USN-94-1: Perl vulnerability

Releases

• Ubuntu 4.10

Details

Paul Szabo discovered another vulnerability in the rmtree() function
in File::Path.pm. While a process running as root (or another user)
was busy deleting a directory tree, a different user could exploit a
race condition to create setuid binaries in this directory tree,
provided that he already had write permissions in any subdirectory of
that tree.

Update instructions

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

Ubuntu 4.10

• perl-modules -

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