Perl CGI.pm header injection
|perl-cgipm-header-injection (80098)||Medium Risk|
Perl CGI.pm is vulnerable to HTTP header injection, caused by improper validation of input. By persuading a victim to visit a specially-crafted Web page, a remote attacker could exploit this vulnerability to inject arbitrary Set-Cookie and P3P HTTP headers, which will allow the attacker to conduct various attacks against the vulnerable system, including cross-site scripting, cache poisoning or session hijacking.
Upgrade to the latest version of CGI.pm (3.63 or later), available from the Search.cpan Web site. See References.
For other distributions:
Apply the appropriate update for your system. See References.
