nss: Memory corruption in decodeECorDsaSignature with DSA signatures (and RSA-PSS)

A remote code execution flaw was found in the way NSS verifies certificates. This flaw allows an attacker posing as an SSL/TLS server to trigger this issue in a client application compiled with NSS when it tries to initiate an SSL/TLS connection. Similarly, a server application compiled with NSS,...

UBUNTU-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...
