A vulnerability was discovered and corrected in perl-CGI-Simple:

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 (CVE-2010-2761).

The updated packages have been patched to correct this issue.
