Multiple buffer overflows in Ipswitch WS_FTP Server 5.05 before Hotfix 1 allow remote authenticated users to execute arbitrary code via long (1) XCRC, (2) XSHA1, or (3) XMD5 commands.
Ipswitch WS_FTP Server 4.0.2 allows remote attackers to cause a denial of service (disk consumption) and bypass file size restrictions via a REST command with a large size argument, followed by a STOR of a smaller file.
Multiple buffer overflows in WS_FTP 3 and 4 allow remote authenticated users to cause a denial of service and possibly execute arbitrary code via long (1) APPE (append) or (2) STAT (status) arguments.
