Publication date: 02 Dec 2021
URL: https://advisories.mageia.org/MGASA-2021-0534.html
Type: security
Affected Mageia releases: 8
CVE: 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 NSS for certificate validation or other TLS, X.509, OCSP or CRL
functionality may be impacted, depending on how they configure NSS
(CVE-2021-43527).

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.
