Multiple heap-based buffer overflows in Titan FTP Server 6.03 and 6.0.5.549 allow remote attackers to cause a denial of service (daemon crash or hang) and possibly execute arbitrary code via a long argument to the (1) USER or (2) PASS command, different vectors than CVE-2004-1641.

Heap-based buffer overflow in Titan FTP Server 6.05 build 550 allows remote attackers to execute arbitrary code via a long DELE command.

Titan FTP Server version 3.01 build 163, and possibly other versions before build 169, allows remote authenticated users to cause a denial of service (crash) by disconnecting from the system during a "LIST -L" command, which causes Titan to access an invalid socket.

Heap-based buffer overflow in Titan FTP 3.21 and earlier allows remote attackers to cause a denial of service (crash) via a long FTP command such as (1) CWD, (2) STAT, or (3) LIST.
