K20145801: Mozilla NSS vulnerability CVE-2016-1979

Security Advisory Description Use-after-free vulnerability in the PK11ImportDERPrivateKeyInfoAndReturnKey function in Mozilla Network Security Services NSS before 3.21.1, as used in Mozilla Firefox before 45.0, allows remote attackers to cause a denial of service or possibly have unspecified othe...

SUSE CVE-2014-1569

The definitelengthdecoder function in lib/util/quickder.c in Mozilla Network Security Services NSS before 3.16.2.4 and 3.17.x before 3.17.3 does not ensure that the DER encoding of an ASN.1 length is properly formed, which allows remote attackers to conduct data-smuggling attacks by using a long...

SUSE CVE-2019-14853

An error-handling flaw was found in python-ecdsa before version 0.13.3. During signature decoding, malformed DER signatures could raise unexpected exceptions or no exceptions at all, which could lead to a denial of service...

SUSE CVE-2019-14859

A flaw was found in all python-ecdsa versions before 0.13.3, 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...
