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...

ALPINE-CVE-2021-43527

NSS Network Security Services versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures encoded within CMS, S/MIME, PKCS \7, or PKCS \12 are likely to be impacted. Applications using N...

python-ecdsa: DER encoding is not being verified in signatures

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...
