leading to symlink attacks.

Background

  1  net-analyzer/honeyd      < 1.5c-r1                     >=3D 1.5c-r1

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Dmitry E. Oboukhov reported an insecure temporary file usage within the
"test.sh" script.

Impact
=3D=3D=3D=3D=3D=3D

A local attacker could perform symlink attacks and overwrite arbitrary
files with the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All Honeyd users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=3Dnet-analyzer/honeyd-1.5c-r1"
