|Gentoo Linux Security Advisory
Title: Screenie: Insecure temporary file usage (GLSA 200909-09)
Date: September 09, 2009
An insecure temporary file usage has been reported in Screenie, allowing
for symlink attacks.
Screenie is a small screen frontend that is designed to be a session
Vulnerable: < 1.30.0-r1
Unaffected: >= 1.30.0-r1
Architectures: All supported architectures
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"
