Package : proftpd Vulnerability : potential code execution Problem-Type : format string error Debian-specific: no CVE ID : CAN-2005-2390

infamous42md reported that proftpd suffers from two format string vulnerabilities. In the first, a user with the ability to create a directory could trigger the format string error if there is a proftpd shutdown message configured to use the "%C", "%R", or "%U" variables. In the second, the error is triggered if mod_sql is used to retrieve messages from a database and if format strings have been inserted into the database by a user with permission to do so.

There was a build error for the sarge i386 proftpd packages released in DSA 795-1. A new build, 1.2.10-15sarge1.0.1, has been prepared to correct this error. The packages for other architectures are unaffected.
