Comment: This advisory references vulnerabilities in products which run on

Package        : python-crypto
Version        : 2.6-4+deb7u8
CVE ID         : CVE-2018-6594
Debian Bug     : 889999


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).

For Debian 7 "Wheezy", these problems have been fixed in version
2.6-4+deb7u8.

We recommend that you upgrade your python-crypto packages.

these updates to your system and frequently asked questions can be
