CVSS: 7.5EPSS: 27%CPEs: 28EXPL: 1CVE-2021-4044 – Invalid handling of X509_verify_cert() internal errors in libssl
https://notcve.org/view.php?id=CVE-2021-4044
14 Dec 2021 — Internally libssl in OpenSSL calls X509_verify_cert() on the client side to verify a certificate supplied by a server. That function may return a negative return value to indicate an internal error (for example out of memory). Such a negative return value is mishandled by OpenSSL and will cause an IO function (such as SSL_connect() or SSL_do_handshake()) to not indicate success and a subsequent call to SSL_get_error() to return the value SSL_ERROR_WANT_RETRY_VERIFY. This return value is only supposed to be ... • https://github.com/phirojshah/CVE-2021-4044 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

01 Dec 2021 — 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 clien... • https://packetstorm.news/files/id/165110 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
