Ubuntu 20.04: 2021-342-02 critical: gnome-shell privilege escalation
Summary
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. For more information, see: https://www.mozilla.org/en-US/security/advisories/mfsa2021-51/ https:...
