Debian 3.0 DSA 447-2 Urgent: Hsftp Buffer Overflow Remote Attack

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.

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

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you update your hsftp package.
