Vulnerability Assessment Details

Fedora Core 1 2003-034: lftp

Vulnerability Assessment Summary
Check for the version of the lftp package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory FEDORA-2003-034 (lftp).

LFTP is a sophisticated ftp/http file transfer program. Like bash, it
has job control and uses the readline library for input. It has
bookmarks, built-in mirroring, and can transfer several files in
parallel. It is designed with reliability in mind.

Update Information:

Ulf Härnhammar found a remotely-triggerable buffer overflow in lftp.

A possible hacker 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
upgrade lftp to a version which is not vulnerable to this issue.

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