Synopsis An error in the hostname matching of IO::Socket::SSL might enable remote attackers to conduct man-in-the-middle attacks. Background IO::Socket::SSL is a Perl class implementing an object oriented interface to SSL sockets. Description The vendor reported that IO::Socket::SSL does not properly handle Common Name (CN) fields. Impact A remote attacker might employ a specially crafted certificate to conduct man-in-the-middle attacks on SSL connections made using IO::Socket::SSL. Workaround There is no known workaround at this time. Resolution All IO::Socket::SSL users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-perl/IO-Socket-SSL-1.26" References [ 1 ] CVE-2009-3024 : http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3024 Availability This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201101-06.xml |
