CVSS: 8.8EPSS: 0%CPEs: 7EXPL: 1CVE-2022-42898 – krb5: integer overflow vulnerabilities in PAC parsing
https://notcve.org/view.php?id=CVE-2022-42898
PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has "a similar bug." El análisis sintáctico de PAC en MIT Kerberos 5 (también conocido como krb5) antes de 1.19.4 y 1.20.x antes de 1.20.1 tiene desbordamientos de enteros que pueden conducir a la ejecución remota de código (en KDC, kadmind, o un servidor de aplicaciones GSS o Kerberos) en plataformas de 32 bits (que tienen un desbordamiento de búfer resultante), y causar una denegación de servicio en otras plataformas. Esto ocurre en krb5_pac_parse en lib/krb5/krb/pac.c. • https://bugzilla.samba.org/show_bug.cgi?id=15203 https://github.com/heimdal/heimdal/security/advisories/GHSA-64mq-fvfj-5x3c https://github.com/krb5/krb5/commit/ea92d2f0fcceb54a70910fa32e9a0d7a5afc3583 https://security.gentoo.org/glsa/202309-06 https://security.gentoo.org/glsa/202310-06 https://security.netapp.com/advisory/ntap-20230216-0008 https://security.netapp.com/advisory/ntap-20230223-0001 https://web.mit.edu/kerberos/advisories https://web.mit.edu/kerberos/krb5-1.19 https://web& • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2022-2031
A flaw was found in Samba. The security vulnerability occurs when KDC and the kpasswd service share a single account and set of keys, allowing them to decrypt each other's tickets. A user who has been requested to change their password, can exploit this flaw to obtain and use tickets to other services. Se ha encontrado un fallo en Samba. Una vulnerabilidad de seguridad es producida cuando el KDC y el servicio kpasswd comparten una misma cuenta y un mismo conjunto de claves, lo que les permite descifrar los tickets del otro. • https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2022-2031.html • CWE-287: Improper Authentication CWE-288: Authentication Bypass Using an Alternate Path or Channel •

https://notcve.org/view.php?id=CVE-2022-32744
A flaw was found in Samba. The KDC accepts kpasswd requests encrypted with any key known to it. By encrypting forged kpasswd requests with its own key, a user can change other users' passwords, enabling full domain takeover. Se ha encontrado un fallo en Samba. El KDC acepta solicitudes kpasswd cifradas con cualquier clave que conozca. • https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2022-32744.html • CWE-290: Authentication Bypass by Spoofing •

A flaw was found in Samba. Samba AD users can cause the server to access uninitialized data with an LDAP add or modify the request, usually resulting in a segmentation fault. Se ha encontrado un fallo en Samba. Los usuarios de AD de Samba pueden hacer que el servidor acceda a datos no inicializados con una solicitud de adición o modificación de LDAP, resultando usualmente en un fallo de segmentación. • https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2022-32745.html • CWE-125: Out-of-bounds Read CWE-908: Use of Uninitialized Resource •
CVSS: 5.9EPSS: 4%CPEs: 3EXPL: 0CVE-2022-32742 – Samba SMB1 Out-Of-Bounds Read Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2022-32742
A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or printer) instead of client-supplied data. The client cannot control the area of the server memory written to the file (or printer). Se ha encontrado un fallo en Samba. Algunas solicitudes de escritura de SMB1 no son comprobaban correctamente para asegurar que el cliente había enviado suficientes datos para completar la escritura, lo que permitía que el contenido de la memoria del servidor fuera escrita en el archivo (o impresora) en lugar de los datos proporcionados por el cliente. • https://lists.debian.org/debian-lts-announce/2024/04/msg00015.html https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2022-32742.html https://access.redhat.com/security/cve/CVE-2022-32742 https://bugzilla.redhat.com/show_bug.cgi?id=2108196 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
