critical Nessus Plugin ID 191374

Language:

Synopsis

The remote CentOS host is missing a security update for nspr.

Description

The remote CentOS Linux 9 host has packages installed that are affected by a vulnerability as referenced in the nss-3.79.0-14.el9 build changelog.

 - 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. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
 (CVE-2021-43527)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the CentOS 9 Stream nspr package.
