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 (1) a 3xx redirect to a URL with a crafted filename or (2) 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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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 (1) a 3xx redirect to a URL with a     crafted filename or (2) 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. (CVE-2010-2253)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote host is affected by the vulnerability described in GLSA-201402-04 (libwww-perl: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in libwww-perl. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to download a specially crafted       file with an application linked against libwww-perl, which could result       in overwritten files or arbitrary code execution by writing to a dotfile       in the user&rsquo;s home directory (such as .bashrc). Additionally, a remote       attacker could perform a Man-in-the-Middle attack.
  Workaround :

    There is no known workaround at this time.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that libwww-perl incorrectly filtered filenames suggested by Content-Disposition headers. If a user were tricked into downloading a file from a malicious site, a remote attacker could overwrite hidden files in the user's directory.
