Honeyd: Insecure temporary file creation

Background

Honeyd is a small daemon that creates virtual hosts on a network.

Description

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

Impact

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

All Honeyd users should upgrade to the latest version:

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