An issue was discovered in Mbed TLS before 2.25.0 (and before 2.16.9 LTS and before 2.7.18 LTS). The calculations performed by mbedtls_mpi_exp_mod are not limited; thus, supplying overly large parameters could lead to denial of service when generating Diffie-Hellman key pairs. Se ha detectado un problema en Mbed TLS versiones anteriores a 2.25.0 (y versiones anteriores a 2.16.9 LTS y versiones anteriores a 2.7.18 LTS). Los cálculos llevado a cabo por la función mbedtls_mpi_exp_mod no están limitados; por lo tanto, el suministro de parámetros demasiado grandes podría conllevar a una denegación de servicio cuando se generan pares de claves Diffie-Hellman. • https://cert-portal.siemens.com/productcert/pdf/ssa-756638.pdf https://github.com/ARMmbed/mbedtls/releases/tag/v2.16.9 https://github.com/ARMmbed/mbedtls/releases/tag/v2.25.0 https://github.com/ARMmbed/mbedtls/releases/tag/v2.7.18 https://lists.debian.org/debian-lts-announce/2021/11/msg00021.html https://lists.debian.org/debian-lts-announce/2022/12/msg00036.html • CWE-131: Incorrect Calculation of Buffer Size •
CVSS: 8.5EPSS: 96%CPEs: 36EXPL: 2CVE-2021-39144 – XStream Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-39144
XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker has sufficient rights to execute commands of the host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose. XStream es una biblioteca sencilla para serializar objetos a XML y viceversa. • http://packetstormsecurity.com/files/169859/VMware-NSX-Manager-XStream-Unauthenticated-Remote-Code-Execution.html https://github.com/x-stream/xstream/security/advisories/GHSA-j9h8-phrw-h4fh https://lists.debian.org/debian-lts-announce/2021/09/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/22KVR6B5IZP3BGQ3HPWIO2FWWCKT3DHP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PVPHZA7VW2RRSDCOIPP2W6O5ND254TU7 https://lists.fedoraproject.org/ • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-306: Missing Authentication for Critical Function CWE-502: Deserialization of Untrusted Data •

An issue was discovered in Mbed TLS before 2.24.0 (and before 2.16.8 LTS and before 2.7.17 LTS). There is missing zeroization of plaintext buffers in mbedtls_ssl_read to erase unused application data from memory. Se ha detectado un problema en Mbed TLS versiones anteriores a 2.24.0 (y versiones anteriores a 2.16.8 LTS y versiones anteriores a 2.7.17 LTS).

An issue was discovered in Mbed TLS before 2.25.0 (and before 2.16.9 LTS and before 2.7.18 LTS). A NULL algorithm parameters entry looks identical to an array of REAL (size zero) and thus the certificate is considered valid. However, if the parameters do not match in any way, then the certificate should be considered invalid. Se ha detectado un problema en Mbed TLS versiones anteriores a 2.25.0 (y versiones anteriores a 2.16.9 LTS y versiones anteriores a 2.7.18 LTS). Una entrada de parámetros de algoritmo NULL parece idéntica a una matriz de REAL (tamaño cero) y, por tanto, el certificado es considerado válido. • https://cert-portal.siemens.com/productcert/pdf/ssa-756638.pdf https://github.com/ARMmbed/mbedtls/issues/3629 https://github.com/ARMmbed/mbedtls/releases/tag/v2.16.9 https://github.com/ARMmbed/mbedtls/releases/tag/v2.25.0 https://github.com/ARMmbed/mbedtls/releases/tag/v2.7.18 https://lists.debian.org/debian-lts-announce/2021/11/msg00021.html https://lists.debian.org/debian-lts-announce/2022/12/msg00036.html • CWE-295: Improper Certificate Validation •

https://notcve.org/view.php?id=CVE-2021-37750
The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.5 and 1.19.x before 1.19.3 has a NULL pointer dereference in kdc/do_tgs_req.c via a FAST inner body that lacks a server field. El Centro de Distribución de Claves (KDC) en MIT Kerberos 5 (también se conoce como krb5) versiones anteriores a 1.18.5 y 1.19.x versiones anteriores a 1.19.3, presenta una desreferencia de puntero NULL en el archivo kdc/do_tgs_req.c por medio de un cuerpo interno FAST que carece de un campo de servidor. A flaw was found in krb5. The Key Distribution Center (KDC) in MIT Kerberos 5 has a NULL pointer dereference via a FAST inner body that lacks a server field. An authenticated attacker could use this flaw to crash the Kerberos KDC server. • https://github.com/krb5/krb5/commit/d775c95af7606a51bf79547a94fa52ddd1cb7f49 https://github.com/krb5/krb5/releases https://lists.debian.org/debian-lts-announce/2021/09/msg00019.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MFCLW7D46E4VCREKKH453T5DA4XOLHU2 https://security.netapp.com/advisory/ntap-20210923-0002 https://web.mit.edu/kerberos/advisories https://www.oracle.com/security-alerts/cpujul2022.html https://www.starwindsoftware.com/security/sw-20220817-0004 https& • CWE-476: NULL Pointer Dereference •
