[slackware-security]  mozilla-nss (SSA:2021-337-01)

New mozilla-nss packages are available for Slackware 14.0, 14.1, 14.2,
and -current to fix a security issue.


Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/mozilla-nss-3.40.1-i586-2_slack14.2.txz:  Rebuilt.
  This update fixes a critical security issue:
  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 they configure NSS.
  Note: This vulnerability does NOT impact Mozilla Firefox. However, email
  clients and PDF viewers that use NSS for signature verification, such as
  Thunderbird, LibreOffice, Evolution and Evince are believed to be impacted.
  Thanks to Tavis Ormandy of Google Project Zero.
