A directory traversal vulnerability has been discovered in Archive::Tar.
|Package||perl-core/Archive-Tar on all architectures|
|Affected versions||< 1.40|
|Unaffected versions||>= 1.40|
Archive::Tar is a Perl module for creation and manipulation of tar files.
Jonathan Smith of rPath reported that Archive::Tar does not check for ".." in file names.
A remote attacker could entice a user or automated system to extract a specially crafted tar archive, overwriting files at arbitrary locations outside of the specified directory.
There is no known workaround at this time.
All Archive::Tar users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=perl-core/Archive-Tar-1.40"
