Synopsis
========

A vulnerability in UUDeview may allow local attackers to conduct
symlink attacks.

Background
==========

UUdeview is encoder and decoder supporting various binary formats.
NZBGet is a command-line based binary newsgrabber supporting .nzb
files.

Affected packages
=================

      -------------------------------------------------------------------
       Package            /   Vulnerable   /                  Unaffected
      -------------------------------------------------------------------
    1  app-text/uudeview      < 0.5.20-r1                   >= 0.5.20-r1
    2  news-nntp/nzbget         < 0.4.0                         >= 0.4.0
      -------------------------------------------------------------------
       2 affected packages on all of their supported architectures.
      -------------------------------------------------------------------

Description
===========

UUdeview makes insecure usage of the tempnam() function when creating
temporary files. NZBGet includes a copy of the vulnerable code.

Impact

A local attacker could exploit this vulnerability to overwrite
arbitrary files on the system.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All UUDview users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=app-text/uudeview-0.5.20-r1"

All NZBget users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=news-nntp/nzbget-0.4.0"
