Marvin Wilke requested to merge dependabot/pip/ecdsa-0.13.3 into master

Created by: dependabot[bot]

Bumps ecdsa from 0.10 to 0.13.3.

Release notes

Sourced from ecdsa's releases.

ecdsa 0.13.3

Fix CVE-2019-14853 - possible DoS caused by malformed signature decoding Fix CVE-2019-14859 - signature malleability caused by insufficient checks of DER encoding

Also harden key decoding from string and DER encodings.

ecdsa 0.13.2

Restore compatibility of setup.py with Python 2.6 and 2.7.

ecdsa 0.13.1

Fix the PyPI wheel - the old version included .pyc files.

ecdsa 0.13

Fix the argument order for Curve constructor (put openssl_name= at the end,
with a default value) to unbreak compatibility with external callers who used
the 0.11 convention.

ecdsa 0.12

Switch to Versioneer for version-string management (fixing the broken ecdsa.__version__ attribute). Add Curve.openssl_name property. Mention secp256k1 in README, test against OpenSSL. Produce "wheel" distributions. Add py3.4 and pypy3 compatibility testing. Other minor fixes.

  • Release 0.11 (10 Mar 2014)

Add signature-encoding functions "sigencode_{strings,string,der}_canonize" which canonicalize the S value (using the smaller of the two possible values). Add "validate_point=" argument to VerifyingKey.from_string() constructor (defaults to True) which can be used to disable time-consuming point validation when importing a pre-validated verifying key. Drop python2.5 support (untested but not explicitly broken yet), update trove classifiers.
