CVEs (cve.mitre.org): CVE-2003-0963

Details

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
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.


Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

If up2date fails to connect to Red Hat Network due to SSL Certificate
Errors, you need to install a version of the up2date client with an updated
certificate. The latest version of up2date is available from the Red Hat
FTP site and may also be downloaded directly from the RHN website:
