Ubuntu 4.10 / 5.04 / 5.10 : fetchmail vulnerability (USN-215-1)

Ubuntu Security Notice (C) 2005-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Thomas Wolff and Miloslav Trmac discovered a race condition in the
fetchmailconf program. The output configuration file was initially
created with insecure permissions, and secure permissions were applied
after writing the configuration into the file. During this time, the
file was world readable on a standard system (unless the user manually
tightened his umask setting), which could expose email passwords to
local users.

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 fetchmail, fetchmail-ssl and / or fetchmailconf
packages.

Risk factor :

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