python-ecdsa vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in python-ecdsa.
Software Description
It was discovered that python-ecdsa incorrectly handled certain signatures. A remote attacker could possibly use this issue to cause python-ecdsa to generate unexpected exceptions, resulting in a denial of service. (CVE-2019-14853)
It was discovered that python-ecdsa incorrectly verified DER encoding in signatures. A remote attacker could use this issue to perform certain malleability attacks. (CVE-2019-14859)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 19.10
python-ecdsa - 0.13.2-2ubuntu0.1
python3-ecdsa - 0.13.2-2ubuntu0.1
Ubuntu 19.04
python-ecdsa - 0.13-3ubuntu0.1
python3-ecdsa - 0.13-3ubuntu0.1
Ubuntu 18.04 LTS
python-ecdsa - 0.13-2ubuntu0.18.04.1
python3-ecdsa - 0.13-2ubuntu0.18.04.1
Ubuntu 16.04 LTS
python-ecdsa - 0.13-2ubuntu0.16.04.1
python3-ecdsa - 0.13-2ubuntu0.16.04.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
