(RHSA-2003:404) lftp security update

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
CAN-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.
