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...
thunderbird: Memory corruption when processing S/MIME messages
A flaw was found in Thunderbird, which is vulnerable to the heap overflow described in CVE-2021-43527 when processing S/MIME messages. Thunderbird versions 91.3.0 and later will not call the vulnerable code when processing S/MIME messages that contain certificates with DER-encoded DSA or RSA-PSS...
