hsftp - format string vulnerability [LWN.net]

Package(s):

hsftp

CVE #(s):

CAN-2004-0159

Created:

February 23, 2004

Updated:

February 25, 2004

Description:

During an audit, Ulf Harnhammar discovered a format string vulnerability in hsftp. This vulnerability could be exploited by an attacker able to create files on a remote server with carefully crafted names, to which a user would connect using hsftp. When the user requests a directory listing, particular bytes in memory could be overwritten, potentially allowing arbitrary code to be executed with the privileges of the user invoking hsftp. Note that while hsftp is installed setuid root, it only uses these privileges to acquire locked memory, and then relinquishes them.
