Red Hat alert RHSA-2003:404-01 (lftp)
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated lftp packages fix security vulnerability Advisory ID: RHSA-2003:404-01 Issue date: 2003-12-16 Updated on: 2003-12-16 Product: Red Hat Enterprise Linux Keywords: Cross references: Obsoletes: CVE Names: CAN-2003-0963 - --------------------------------------------------------------------- 1. Topic: Updated lftp packages are now available that fix a buffer overflow security vulnerability. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux ES version 3 - i386 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 3. Problem description: 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. 4. 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: https://rhn.redhat.com/help/latest-up2date.pxt 5.
