Ubuntu 14.04 LTS : libytnef vulnerabilities (USN-3288-1)

Ubuntu Security Notice (C) 2017 Canonical, Inc. / NASL script (C) 2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that libytnef incorrectly handled malformed TNEF
streams. If a user were tricked into opening a specially crafted TNEF
attachment, an attacker could cause a denial of service or possibly
execute arbitrary code.

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 libytnef0 package.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.8
(CVSS2#E:U/RL:U/RC:C)
