FreeBSD : lftp -- multiple HTTP client download filename vulnerability (29b7e3f4-b6a9-11df-ae63-f255a795cb21)

high Nessus Plugin ID 49108

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

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.

Solution

Update the affected package.
