Debian DLA-1978-1 : python-ecdsa security update

critical Nessus Plugin ID 130407

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that python-ecdsa, a cryptographic signature library for Python, did not correctly verify DER encoded signatures. Malformed signatures could lead to unexpected exceptions and in some cases did not raise any exception.

For Debian 8 'Jessie', these problems have been fixed in version 0.11-1+deb8u1.

We recommend that you upgrade your python-ecdsa 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.

Solution

Upgrade the affected python-ecdsa, and python3-ecdsa packages.
