[DSA447] DSA-447-1 hsftp

Vulnerability Assessment Summary
DSA-447-1 hsftp

Detailed Explanation for this Vulnerability Assessment

Ulf Härnhammar 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 permiting arbitrary code to be executed with
the rights of the user invoking hsftp.
Note that while hsftp is installed setuid root, it only uses these
rights 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.
