Serv-U < 9.1.0.0 TEA Decoder Remote Stack Buffer Overflow

High

Synopsis

The remote host is vulnerable to a remote buffer overflow attack.

Description

The remote host is running Serv-U File Server, an FTP server for Windows. The installed version is earlier than 9.1.0.0. Such versions are potentially affected by a remote buffer overflow vulnerability caused by a boundary error in a function when processing a hexadecimal representation of a string using a TEA decoding algorithm.

Solution

Upgrade to Serv-U version 9.1.0.0 or later.
