<title>LSAT: Insecure temporary file creation</title>
LSAT insecurely creates temporary files which can lead to symlink attacks
allowing a local user to overwrite arbitrary files.

The Linux Security Auditing Tool (LSAT) is a post install security
auditor which checks many system configurations and local network
settings on the system for common security or configuration errors and
for packages that are not needed.
LSAT insecurely writes in /tmp with a predictable filename.
<impact type="low">
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.
There is no known workaround at this time.
All lsat users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-admin/lsat-0.9.5&quot;</code>
