Description

The Archive::Tar module provides a mechanism for Perl scripts to manipulate
tar archive files.

Multiple directory traversal flaws were discovered in the Archive::Tar
module. A specially-crafted tar file could cause a Perl script, using the
Archive::Tar module to extract the archive, to overwrite an arbitrary file
writable by the user running the script. (CVE-2007-4829)

This package upgrades the Archive::Tar module to version 1.39_01. Refer to
the Archive::Tar module's changes file, linked to in the References, for a
full list of changes.

Users of perl-Archive-Tar are advised to upgrade to this updated package,
which corrects these issues. All applications using the Archive::Tar module
must be restarted for this update to take effect.
