The following updates has been released for Debian GNU/Linux:

DLA 1283-2: python-crypto security update
DLA 1342-1: ldap-account-manager security update

DLA 1283-2: python-crypto security update

Package : python-crypto
Version : 2.6-4+deb7u8


This is an update to DLA-1283-1. In DLA-1283-1 it is claimed that the issue
described in CVE-2018-6594 is fixed. It turns out that the fix is partial and
upstream has decided not to fix the issue as it would break compatibility and
that ElGamal encryption was not intended to work on its own.

The recommendation is still to upgrade python-crypto packages. In addition
please take into account that the fix is not complete. If you have an
application using python-crypto is implementing ElGamal encryption you should
consider changing to some other encryption method.

There will be no further update to python-crypto for this specific CVE. A fix
would break compatibility, the problem has been ignored by regular Debian
Security team due to its minor nature and in addition to that we are close to
the end of life of the Wheezy security support.

CVE-2018-6594:

python-crypto generated weak ElGamal key parameters, which allowed attackers to
obtain sensitive information by reading ciphertext data (i.e., it did not have
semantic security in face of a ciphertext-only attack).

We recommend that you upgrade your python-crypto packages.
