Debian DSA-447-1 : hsftp - format string

high Nessus Plugin ID 15284

Synopsis

The remote Debian host is missing a security-related update.

Description

Ulf Harnhammar from the Debian Security Audit Project 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.

Solution

For the current stable distribution (woody) this problem has been fixed in version 1.11-1woody1.

We recommend that you update your hsftp package.
