Updated mailman packages that fix a security issue and various bugs are now available for CentOS Linux 4. This update has been rated as having low security impact by the CentOS Security Response Team.
Mailman is a program used to help manage email discussion lists. A flaw was found in Mailman. A remote attacker could spoof messages in the error log, and possibly trick the administrator into visiting malicious URLs via a carriage return/line feed sequence in the URI. (CVE-2006-4624) As well, these updated packages fix the following bugs: * canceling a subscription on the confirm subscription request page caused mailman to crash. * editing the sender filter caused all spam filter rules to be deleted. * the migrate-fhs script was not included. * the mailman init script returned a zero (success) exit code even when an incorrect command was given. For example, the "mailman foo" command returned a zero exit code. In these updated packages the mailmain init script returns the correct exit codes. Users of Mailman are advised to upgrade to these updated packages, which resolve these issues.
