Debian DLA-1283-1 : python-crypto security update

Medium Nessus Plugin ID 106819


The remote Debian host is missing a security update.


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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Upgrade the affected packages.
