All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the S4U (MS-SFU) Kerberos delegation model includes a feature allowing for a subset of clients to be opted out of constrained delegation in any way, either S4U2Self or regular Kerberos authentication, by forcing all tickets for these clients to be non-forwardable. In AD this is implemented by a user attribute delegation_not_allowed (aka not-delegated), which translates to disallow-forwardable. However the Samba AD DC does not do that for S4U2Self and does set the forwardable flag even if the impersonated client has the not-delegated flag set. Todas las versiones de Samba 4.xx anteriores a 4.9.17, versiones 4.10.x anteriores a 4.10.11 y versiones 4.11.x anteriores a 4.11.3, presentan un problema, donde el modelo de delegación de Kerberos S4U (MS-SFU) incluye una funcionalidad que permite a un subconjunto de clientes ser excluidos de la delegación restringida de cualquier manera, ya sea S4U2Self o autenticación Kerberos regular, al forzar que todos los tickets para estos clientes no sean reenviables. En AD, esto es implementado mediante un atributo de usuario delegation_not_allowed (también se conoce como no delegado), que se traduce como no permitido-reenviable. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00038.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14870 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.debian.org/debian-lts-announce/2022/11/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PJH3ROOFYMOATD2UEPC47P5RPBDTY77E https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WNKA4YIPV7AZR7KK3GW6L3HKGHSGJZFE https: • CWE-285: Improper Authorization CWE-287: Improper Authentication •

radare2 through 4.0.0 lacks validation of the content variable in the function r_asm_pseudo_incbin at libr/asm/asm.c, ultimately leading to an arbitrary write. This allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via crafted input. radare2 versiones hasta 4.0.0, carece de comprobación de la variable de contenido en la función r_asm_pseudo_incbin en el archivo libr/asm/asm.c, finalmente conllevando a una escritura arbitraria. Esto permite a atacantes remotos causar una denegación de servicio (bloqueo de aplicación) o posiblemente tener otro impacto no especificado por medio de una entrada diseñada. • https://github.com/radareorg/radare2/issues/15545 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WRQXCOVFWZIIMAZIAAFAVQGZOS7LGHXP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YQTOWEDFXDTGTD6D4NHRB4FUURQSTTEN • CWE-476: NULL Pointer Dereference •

CVSS: 5.3EPSS: 0%CPEs: 18EXPL: 0CVE-2019-1551 – rsaz_512_sqr overflow bug on x86_64
https://notcve.org/view.php?id=CVE-2019-1551
There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00030.html http://packetstormsecurity.com/files/155754/Slackware-Security-Advisory-openssl-Updates.html https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=419102400a2811582a7a3d4a4e317d72e5ce0a8f https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=f1c5eea8a817075d31e43f5876993c6710238c98 https://lists.debian.org/debian-lts-announce/2022/03/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/messag • CWE-190: Integer Overflow or Wraparound •
