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

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 (CVE-2010-4410).

The updated packages have been patched to correct this issue.
