CVSS: 7.5EPSS: 24%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') •

https://notcve.org/view.php?id=CVE-2021-41182
26 Oct 2021 — jQuery-UI is the official jQuery user interface library. Prior to version 1.13.0, accepting the value of the `altField` option of the Datepicker widget from untrusted sources may execute untrusted code. The issue is fixed in jQuery UI 1.13.0. Any string value passed to the `altField` option is now treated as a CSS selector. A workaround is to not accept the value of the `altField` option from untrusted sources. jQuery-UI es la biblioteca oficial de interfaz de usuario de jQuery. • https://blog.jqueryui.com/2021/10/jquery-ui-1-13-0-released • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
