Description: Two security issues have been reported in ProFTPD, potentially allowing malicious users to bypass certain security restrictions and disclose some sensitive information. 1) An error exists in the handling of certain IP address ACLs. The problem is that a CIDR based ACL entry will act as an "AllowAll" directive. 2) An error in the restrictions for executing the "SITE CHGRP" command when changing group owners can be exploited to change the group owner for arbitrary files. The security issues have been reported in version 1.2.9. Prior versions may also be affected. Solution: Update to version 1.2.10rc1. http://www.proftpd.org/ Provided and/or discovered by: 1) Jindrich Makovicka 2) rasco Changelog: 2004-05-19: Added CVE reference. 2004-12-16: Added information about "site chgrp" vulnerability.
