Detail

Synopsis

Lookup uses temporary files in an insecure manner, allowing for a symlink attack.

Background

Lookup is a search interface to books and dictionnaries for Emacs.

Description

Tatsuya Kinoshita reported that the ndeb-binary function does not handle temporay files correctly.

Impact

A local attacker could use a symlink attack to overwrite files with the privileges of the user running Lookup.

Workaround

There is no known workaround at this time.

Resolution

All Lookup users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-emacs/lookup-1.4.1"
