Ubuntu 5.04 / 5.10 / 6.06 LTS : openssl vulnerability (USN-353-2)

Ubuntu Security Notice (C) 2006-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

USN-353-1 fixed several vulnerabilities in OpenSSL. However, Mark J
Cox noticed that the applied patch for CVE-2006-2940 was flawed. This
update corrects that patch.

For reference, this is the relevant part of the original advisory :

Certain types of public key could take disproportionate amounts of
time to process. The library now limits the maximum key exponent size
to avoid Denial of Service attacks. (CVE-2006-2940).

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 packages.

Risk factor :

High / CVSS Base Score : 7.8
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:C)
CVSS Temporal Score : 6.8
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
