USN-700-1 fixed vulnerabilities in Perl. Due to problems with the Ubuntu
8.04 build, some Perl .ph files were missing from the resulting update.
This update fixes the problem. We apologize for the inconvenience.

Original advisory details:

Jonathan Smith discovered that the Archive::Tar Perl module did not
correctly handle symlinks when extracting archives. If a user or
automated system were tricked into opening a specially crafted tar file,
a remote attacker could over-write arbitrary files. (CVE-2007-4829)

Tavis Ormandy and Will Drewry discovered that Perl did not correctly
handle certain utf8 characters in regular expressions. If a user or
automated system were tricked into using a specially crafted expression,
a remote attacker could crash the application, leading to a denial
of service. Ubuntu 8.10 was not affected by this issue. (CVE-2008-1927)

A race condition was discovered in the File::Path Perl module’s rmtree
function. If a local attacker successfully raced another user’s call
of rmtree, they could create arbitrary setuid binaries. Ubuntu 6.06
and 8.10 were not affected by this issue. (CVE-2008-5302)

A race condition was discovered in the File::Path Perl module’s rmtree
function. If a local attacker successfully raced another user’s call of
rmtree, they could delete arbitrary files. Ubuntu 6.06 was not affected
by this issue. (CVE-2008-5303)
