Debian Security Advisory DSA-4588-1 [email protected]
https://www.debian.org/security/ Sebastien Delafond
December 17, 2019 https://www.debian.org/security/faq
Package : python-ecdsa
CVE ID : CVE-2019-14853 CVE-2019-14859
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.
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.
We recommend that you upgrade your python-ecdsa packages.
For the detailed security status of python-ecdsa please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/python-ecdsa
