Description Stefan Behte (RETIRED) gentoo-dev Security 2010-07-26 15:40:43 UTC
CVE-2010-2251 (
  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.

> Please remove vulnerable versions.

We're not done stabilising 4.0.9 yet (bug #327979).

Arches, please continue stabilising:
Target KEYWORDS="alpha amd64 arm hppa ia64 mips ppc ppc64 s390 sparc x86"

Stable for PPC.
