Screenie: Insecure temporary file usage — GLSA 200909-09

An insecure temporary file usage has been reported in Screenie, allowing for symlink attacks.

Affected Packages

app-misc/screenie on all architectures
Affected versions < 1.30.0-r1
Unaffected versions >= 1.30.0-r1

Background

Screenie is a small screen frontend that is designed to be a session handler.

Description

Dmitry E. Oboukhov reported that Screenie does not handle "/tmp/.screenie.#####" temporary files securely.

Impact

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

Workaround

There is no known workaround at this time.

Resolution

All Screenie users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-misc/screenie-1.30.0-r1"
