Fedora 14 : proftpd-1.3.3d-1.fc14 (2011-0610)
Medium Nessus Plugin ID 51820
SynopsisThe remote Fedora host is missing a security update.
DescriptionThis is an update to the current upstream maintenance release, which addresses a security issue that could affect users of the mod_sql module (not enabled by default).
- A heap-based buffer overflow flaw was found in the way ProFTPD FTP server prepared SQL queries for certain usernames, when the mod_sql module was enabled. A remote, unauthenticated attacker could use this flaw to cause the proftpd daemon to crash or, potentially, to execute arbitrary code with the privileges of the user running 'proftpd' via a specially crafted username, provided in the authentication dialog.
The update also fixes a CPU spike when handling .ftpaccess files, and handling of SFTP uploads when compression is used.
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected proftpd package.
