ECDSA signature validation vulnerability by accepting wrong ASN.1 encoding in jsrsasign

Impact Jsrsasign supports ECDSA signature validation which signature value is represented by ASN.1 DER encoding. This vulnerablity may accept a wrong ASN.1 DER encoded ECDSA signature such as: - wrong multi-byte ASN.1 length of TLV ex. 0x820045 even though 0x45 is correct - prepending zeros with...

According to the version of the python2-ecdsa package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability : - A flaw was found in python-ecdsa, where it did not correctly verify whether signatures used DER encoding. Without...

USN-4376-1: OpenSSL vulnerabilities | Cloud Foundry

Severity Low Vendor Canonical Ubuntu Versions Affected Canonical Ubuntu 16.04 Canonical Ubuntu 18.04 Description Cesar Pereida García, Sohaib ul Hassan, Nicola Tuveri, Iaroslav Gridin, Alejandro Cabrera Aldaya, and Billy Brumley discovered that OpenSSL incorrectly handled ECDSA signatures. An...

Malleable ECDSA Signature

jsrsasign uses a malleable ECDSA signature. The vulnerability exists as it does not check for overflows in the length of a sequence, and allows 0 characters appended or prepended to an integer to be verified as the same as without the extra 0 characters...

CVE-2020-14966

An issue was discovered in the jsrsasign package through 8.0.18 for Node.js. It allows a malleability in ECDSA signatures by not checking overflows in the length of a sequence and '0' characters appended or prepended to an integer. The modified signatures are verified as valid. This could have a...
