CVE-2019-14859

A flaw was found in python-ecdsa, where it did not correctly verify whether signatures used DER encoding. Without this verification, a malformed signature could be accepted, making the signature malleable. Without proper verification, an attacker could use a malleable signature to create false...

security/py-ecdsa -- multiple issues

py-ecdsa developers report: Fix CVE-2019-14853 - possible DoS caused by malformed signature decoding. Fix CVE-2019-14859 - signature malleability caused by insufficient checks of DER encoding...

Denial Of Service (DoS)

libtasn1.so is vulnerable to denial of service DoS. The attack exists because it allows a two-byte stack overflow while decoding DER encoded data in asn1derdecoding, leading to the DoS attack and possibly other attacks...
