Description Vincent Danen 2011-03-03 01:48:48 UTC

An integer overflow flaw was reported [1],[2] in the mod_sftp module of ProFTPD.  If a specially crafted SSH message was sent to a ProFTPD server using mod_sftp, it could lead to the allocation of enormous amounts of memory and an eventual OOM termination by the kernel.  This issue was assigned the name CVE-2011-1137 [3].  It was fixed in CVS [4],[5],[6]
