Debian DSA-4588-1 : python-ecdsa - security update

critical Nessus Plugin ID 132110

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

It was discovered that python-ecdsa, a cryptographic signature library for Python, incorrectly handled certain signatures. A remote attacker could use this issue to cause python-ecdsa to either not warn about incorrect signatures, or generate exceptions resulting in a denial-of-service.

Solution

Upgrade the python-ecdsa packages.

For the oldstable distribution (stretch), these problems have been fixed in version 0.13-2+deb9u1.

For the stable distribution (buster), these problems have been fixed in version 0.13-3+deb10u1.
