Mandriva Linux Security Advisory : perl-CGI (MDVSA-2010:237)
Medium Nessus Plugin ID 50609
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionA new version of the CGI Perl module has been released to CPAN, which fixes several security bugs which directly affect Bugzilla (these two security bugs where first discovered as affecting Bugzilla, then identified as being bugs in CGI.pm itself).
The multipart_init function in (1) CGI.pm before 3.50 and (2) Simple.pm in CGI::Simple 1.112 and earlier uses a hard-coded 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).
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).
Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:
