Bugzilla: 591580: CVE-2010-2251 lftp: multiple HTTP client download filename vulnerability [OCERT 2010-001]


The MITRE CVE dictionary describes this issue as:

The get1 command, as used by lftpget, in LFTP before 4.0.6 does not properly validate a server-provided filename before determining the destination filename of a download, which allows remote servers to create or overwrite arbitrary files via a Content-Disposition header that suggests a crafted filename, and possibly execute arbitrary code as a consequence of writing to a dotfile in a home directory.

This issue did not affect the version of lftp as shipped with Red Hat Enterprise Linux 3 and 4 as they did not include support for renaming files to a server-suggested file name.
