> DESCRIPTION:
> A vulnerability has been reported in mod_perl, which potentially can
> be exploited by malicious people to cause a DoS (Denial of Service).
> 
> The vulnerability is caused due to a regular expression in
> "RegistryCooker.pm" (mod_perl 2.x) or "PerlRun.pm" (mod_perl 1.x)
> that uses the "path_info" variable without properly escaping it. This
> can be exploited to cause a DoS by sending requests with specially
> crafted URLs to a vulnerable server.
> 
> SOLUTION:
> Fixed in the SVN repository.
