Background ========== Mod_perl is an Apache module that embeds the Perl interpreter within the server, allowing Perl-based web-applications to be created. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apache/mod_perl < 1.30 >= 1.30 >= 2.0.3-r1 www-apache/mod_perl < 2.0.3-r1 >= 1.30 >= 2.0.3-r1 Description =========== Alex Solvey discovered that the "path_info" variable used in file RegistryCooker.pm (mod_perl 2.x) or file PerlRun.pm (mod_perl 1.x), is not properly escaped before being processed. Impact ====== A remote attacker could send a specially crafted URL to the vulnerable server, possibly resulting in a massive resource consumption. Workaround ========== There is no known workaround at this time. Resolution ========== All mod_perl 1.x users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apache/mod_perl-1.30" All mod_perl 2.x users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apache/mod_perl-2.0.3-r1" References ========== [ 1 ] CVE-2007-1349 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1349 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200705-04.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
