USN-4196-1: python-ecdsa vulnerabilities

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 encodi...

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

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...

Package : python-ecdsa Version : 0.11-1+deb8u1 CVE ID : CVE-2019-14853 CVE-2019-14859 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...

Improper Verification of Cryptographic Signature in keycloak

It was found that Keycloak's SAML broker, versions up to 6.0.1, did not verify missing message signatures. If an attacker modifies the SAML Response and removes the sections, the message is still accepted, and the message can be modified. An attacker could use this flaw to impersonate other users...

Amazon Linux 2 : ruby (ALAS-2019-1276)

It was found that WEBrick could be forced to use an excessive amount of memory during the processing of HTTP requests, leading to a Denial of Service. An attacker could use this flaw to send huge requests to a WEBrick application, resulting in the server running out of memory. CVE-2018-8777 It wa...

Improper Verification Of Cryptographic Signature

openpgp.js is performs improper verification of cryptographic signature. The vulnerability exists as openpgp.js incorrectly trusts unhashed signature subpackets...

Digital Signature Bypass

openpgp.js is vulnerable to digital signature bypass. The vulnerability exists through an improper verification of a cryptographic signature which allows adversaries to replace signatures with a standalone or timestamp signature...
