it would probably be nice to add a note to the CVE that apps/modules should start to implement proper certificate checking and that it got easier with newer IO::Socket::SSL versions.
There isn't really a place in CVE to do this. The description is primarily to describe the problem in a way that allows us to distinguish this issue from other issues. I've included your post as a reference, however. - Steve ====================================================== Name: CVE-2009-3024 Status: Candidate URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3024 Reference: MLIST:[oss-security] 20090828 CVE request: perl-IO-Socket-SSL certificate hostname compare bug Reference: URL:http://www.openwall.com/lists/oss-security/2009/08/28/1 Reference: MLIST:[oss-security] 20090829 Re: CVE request: perl-IO-Socket-SSL certificate hostname compare bug Reference: URL:http://www.openwall.com/lists/oss-security/2009/08/29/1 Reference: MLIST:[oss-security] 20090831 Re: Re: CVE request: perl-IO-Socket-SSL certificate hostname compare bug Reference: URL:http://www.openwall.com/lists/oss-security/2009/08/31/4 Reference: CONFIRM:http://cpansearch.perl.org/src/SULLR/IO-Socket-SSL-1.30/Changes The verify_hostname_of_cert function in the certificate checking feature in IO-Socket-SSL (IO::Socket::SSL) 1.14 through 1.25 only matches the prefix of a hostname when no wildcard is used, which allows remote attackers to bypass the hostname check for a certificate.
