Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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 NSS for
certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how
