CRLF injection vulnerability in the header function in (1) CGI.pm before 3.50 and (2) Simple.pm in CGI::Simple 1.112 and earlier allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via vectors related to non-whitespace characters preceded by newline characters, a different vulnerability than CVE-2010-2761 and CVE-2010-3172.

The multipart_init function in (1) CGI.pm before 3.50 and (2) Simple.pm in CGI::Simple 1.112 and earlier uses a hardcoded value of the MIME boundary string in multipart/x-mixed-replace content, which allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via crafted input that contains this value, a different vulnerability than CVE-2010-3172.
