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

high Nessus Plugin ID 12441
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Red Hat host is missing a security update.


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 Harnhammar 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 Harnhammar for discovering and alerting us to this issue.


Update the affected lftp package.
