Ubuntu 8.04 LTS / 10.04 LTS / 10.10 / 11.04 : postgresql-8.3, postgresql-8.4 vulnerability (USN-1229-1)

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


Synopsis :

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

Description :

It was discovered that the blowfish algorithm in the pgcrypto module
incorrectly handled certain 8-bit characters, resulting in the
password hashes being easier to crack than expected. An attacker who
could obtain the password hashes would be able to recover the
plaintext with less effort.

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 postgresql-8.3 and / or postgresql-8.4 packages.

Risk factor :

Medium / CVSS Base Score : 5.0
(CVSS2#AV:N/AC:L/Au:N/C:P/I:N/A:N)
CVSS Temporal Score : 4.3
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
