GLSA-200506-08 : GNU shtool, ocaml-mysql: Insecure temporary file creation

This script is Copyright (C) 2005-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200506-08
(GNU shtool, ocaml-mysql: Insecure temporary file creation)

Eric Romang has discovered that GNU shtool insecurely creates
temporary files with predictable filenames (CAN-2005-1751). On closer
inspection, Gentoo Security discovered that the shtool temporary file,
once created, was being reused insecurely (CAN-2005-1759).

Impact :

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

Workaround :

There is no known workaround at this time.

Solution :

All GNU shtool users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-util/shtool-2.0.1-r2'
All ocaml-mysql users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-ml/ocaml-mysql-1.0.3-r1'

Risk factor :

Low / CVSS Base Score : 3.7
