GLSA-200411-15 : OpenSSL, Groff: Insecure tempfile handling

This script is Copyright (C) 2004-2014 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-200411-15
(OpenSSL, Groff: Insecure tempfile handling)

groffer and the der_chop script create temporary files in
world-writeable directories with predictable names.

Impact :

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

Workaround :

There is no known workaround at this time.

Solution :

All Groff users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose sys-apps/groff
All OpenSSL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-libs/openssl-0.9.7d-r2'
Note: /etc/ssl/misc/der_chop is protected by Portage as a configuration
file. Don't forget to use etc-update and overwrite the old version with
the new one.

Risk factor :

Low / CVSS Base Score : 2.1
(CVSS2#AV:L/AC:L/Au:N/C:N/I:P/A:N)
