https://notcve.org/view.php?id=CVE-2020-7463
In FreeBSD 12.1-STABLE before r364644, 11.4-STABLE before r364651, 12.1-RELEASE before p9, 11.4-RELEASE before p3, and 11.3-RELEASE before p13, improper handling in the kernel causes a use-after-free bug by sending large user messages from multiple threads on the same SCTP socket. The use-after-free situation may result in unintended kernel behaviour including a kernel panic. En FreeBSD versiones 12.1-STABLE anteriores a r364644, 11.4-STABLE anteriores a r364651, 12.1-RELEASE anteriores a p9, 11.4-RELEASE anteriores a p3 y 11.3-RELEASE anteriores a p13, el manejo inapropiado en el kernel causa un bug de uso de la memoria previamente liberada mediante el envío de mensajes de usuario grandes de múltiples subprocesos en el mismo socket SCTP. La situación del uso de la memoria previamente liberada puede resultar en un comportamiento del kernel no deseado, incluyendo un pánico del kernel. • http://seclists.org/fulldisclosure/2021/Apr/49 http://seclists.org/fulldisclosure/2021/Apr/50 http://seclists.org/fulldisclosure/2021/Apr/57 http://seclists.org/fulldisclosure/2021/Apr/58 http://seclists.org/fulldisclosure/2021/Apr/59 https://security.FreeBSD.org/advisories/FreeBSD-SA-20:25.sctp.asc https://support.apple.com/kb/HT212317 https://support.apple.com/kb/HT212318 https://support.apple.com/kb/HT212319 https://support.apple.com/kb/HT212321 https://support.app • CWE-416: Use After Free •

CVSS: 5.9EPSS: 0%CPEs: 38EXPL: 0CVE-2021-23841 – Null pointer deref in X509_issuer_and_serial_hash()
https://notcve.org/view.php?id=CVE-2021-23841
The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a potential denial of service attack. The function X509_issuer_and_serial_hash() is never directly called by OpenSSL itself so applications are only vulnerable if they use this function directly and they use it on certificates that may have been obtained from untrusted sources. OpenSSL versions 1.1.1i and below are affected by this issue. • http://seclists.org/fulldisclosure/2021/May/67 http://seclists.org/fulldisclosure/2021/May/68 http://seclists.org/fulldisclosure/2021/May/70 https://cert-portal.siemens.com/productcert/pdf/ssa-637483.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=122a19ab48091c657f7cb1fb3af9fc07bd557bbf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=8252ee4d90f3f2004d3d0aeeed003ad49c9a7807 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44846 https://security.gentoo.org/gls • CWE-476: NULL Pointer Dereference •
