Ubuntu 10.04 LTS / 10.10 / 11.04 : puppet vulnerabilities (USN-1223-1)

Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

It was discovered that Puppet unsafely opened files when the k5login
type is used to manage files. A local attacker could exploit this to
overwrite arbitrary files which could be used to escalate privileges.
(CVE-2011-3869)

Ricky Zhou discovered that Puppet did not drop privileges when
creating SSH authorized_keys files. A local attacker could exploit
this to overwrite arbitrary files as root. (CVE-2011-3870)

It was discovered that Puppet used a predictable filename when using
the --edit resource. A local attacker could exploit this to edit
arbitrary files or run arbitrary code as the user invoking the
program, typically root. (CVE-2011-3871).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected puppet-common package.

Risk factor :

Medium / CVSS Base Score : 6.3
