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 •

An issue was discovered in the Linux kernel before 5.10. drivers/infiniband/core/ucma.c has a use-after-free because the ctx is reached via the ctx_list in some ucma_migrate_id situations where ucma_close is called, aka CID-f5449e74802c. Se ha detectado un problema en el kernel de Linux versiones anteriores a 5.10. El archivo drivers/infiniband/core/ucma.c, presenta un uso de la memoria previamente liberada porque el ctx es alcanzado por medio de la función ctx_list en algunas situaciones donde la función ucma_migrate_id en que la función ucma_close, es llamada también se conoce como CID-f5449e74802c An issue was discovered in the Linux kernels Userspace Connection Manager Access for RDMA.

https://notcve.org/view.php?id=CVE-2021-20271
A flaw was found in RPM's signature check functionality when reading a package file. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package, whose signature header was modified, to cause RPM database corruption and execute code. The highest threat from this vulnerability is to data integrity, confidentiality, and system availability. Se detectó un fallo en la funcionalidad de comprobación de firmas de RPM cuando se lee un archivo de paquete. Este fallo permite a un atacante que pueda convencer a una víctima de instalar un paquete aparentemente verificable, cuyo encabezado de firma fue modificado, causar una corrupción de la base de datos de RPM y ejecutar código. • https://bugzilla.redhat.com/show_bug.cgi?id=1934125 https://github.com/rpm-software-management/rpm/commit/d6a86b5e69e46cc283b1e06c92343319beb42e21 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TMGXO3W6DHPO62GJ4VVF5DEUX5DRUR5K https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VHRPNBCRPDJHHQE3MBPSZK4H7X2IM7AC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YILPBTPSBRYL4POBI3F4YUSVPSOQNJBY https://security.gentoo.org/glsa/ • CWE-345: Insufficient Verification of Data Authenticity •
