FreeBSD : p5-libwww -- possibility to remote servers to create file with a .(dot) character (3a7c5fc4-b50c-11df-977b-ecc31dd8ad06)

Synopsis :

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

Description :

lwp-download in libwww-perl before 5.835 does not reject downloads to
filenames that begin with a `.' (dot) character, which allows remote
servers to create or overwrite files via a 3xx redirect to a URL with
a crafted filename or 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.
