CVE-2010-2251 Information

Description

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.
