RHEL 2.1 / 3 : lftp (RHSA-2003:404)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing a security update.

Description :

Updated lftp packages are now available that fix a buffer overflow
security vulnerability.

lftp is a command-line file transfer program supporting FTP and HTTP
protocols.

Ulf Härnhammar discovered a buffer overflow bug in versions of lftp
up to and including 2.6.9. An attacker could create a carefully
crafted directory on a website such that, if a user connects to that
directory using the lftp client and subsequently issues a 'ls' or
'rels' command, the attacker could execute arbitrary code on the users
machine. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2003-0963 to this issue.

Users of lftp are advised to upgrade to these erratum packages, which
contain a backported security patch and are not vulnerable to this
issue.

Red Hat would like to thank Ulf Härnhammar for discovering and
alerting us to this issue.
