Description :

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)
