Synopsis
The remote CentOS host is missing a security update.Description
An updated lftp package that fixes one security issue is now available for Red Hat Enterprise Linux 5.The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
LFTP is a sophisticated file transfer program for the FTP and HTTP protocols. 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.
It was discovered that lftp trusted the file name provided in the Content-Disposition HTTP header. A malicious HTTP server could use this flaw to write or overwrite files in the current working directory of a victim running lftp, by sending a different file from what the victim requested. (CVE-2010-2251)
To correct this flaw, the following changes were made to lftp: the 'xfer:clobber' option now defaults to 'no', causing lftp to not overwrite existing files, and a new option, 'xfer:auto-rename', which defaults to 'no', has been introduced to control whether lftp should use server-suggested file names. Refer to the 'Settings' section of the lftp(1) manual page for additional details on changing lftp settings.
All lftp users should upgrade to this updated package, which contains a backported patch to correct this issue.
