GLSA-200703-20 : LSAT: Insecure temporary file creation

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200703-20
(LSAT: Insecure temporary file creation)

LSAT insecurely writes in /tmp with a predictable filename.

Impact :

A local attacker could create symbolic links in the temporary files
directory, pointing to a valid file somewhere on the filesystem. When
the LSAT script is executed, this would result in the file being
overwritten with the rights of the user running the software, which
could be the root user.

Workaround :

There is no known workaround at this time.

Solution :

All lsat users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-admin/lsat-0.9.5'

Risk factor :

Medium / CVSS Base Score : 4.3
