An insecure temporary file usage has been reported in Screenie, allowing for symlink attacks.
|Package||app-misc/screenie on all architectures|
|Affected versions||< 1.30.0-r1|
|Unaffected versions||>= 1.30.0-r1|
Screenie is a small screen frontend that is designed to be a session handler.
Dmitry E. Oboukhov reported that Screenie does not handle "/tmp/.screenie.#####" temporary files securely.
A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application.
There is no known workaround at this time.
All Screenie users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-misc/screenie-1.30.0-r1"
