CVE-2022-3437
https://notcve.org/view.php?id=CVE-2022-3437
A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the application, possibly resulting in a denial of service (DoS) attack. Se encontró una vulnerabilidad de desbordamiento de búfer en Samba dentro de las rutinas GSSAPI unwrap_des() y unwrap_des3() de Heimdal. Las rutinas de descifrado DES y Triple-DES de la biblioteca GSSAPI de Heimdal permiten un desbordamiento del búfer de escritura de longitud limitada en la memoria asignada a malloc() cuando se presenta un paquete maliciosamente pequeño. • http://www.openwall.com/lists/oss-security/2023/02/08/1 https://access.redhat.com/security/cve/CVE-2022-3437 https://bugzilla.redhat.com/show_bug.cgi?id=2137774 https://lists.debian.org/debian-lts-announce/2024/04/msg00015.html https://security.gentoo.org/glsa/202309-06 https://security.gentoo.org/glsa/202310-06 https://security.netapp.com/advisory/ntap-20230216-0008 https://www.samba.org/samba/security/CVE-2022-3437.html • CWE-122: Heap-based Buffer Overflow •
CVE-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 •
CVE-2022-1615 – samba: GnuTLS gnutls_rnd() can fail and give predictable random values
https://notcve.org/view.php?id=CVE-2022-1615
In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values. En Samba, la función GnuTLS gnutls_rnd() puede fallar y dar valores aleatorios predecibles A flaw was found in Samba. When the gnutls_rnd function is called, its return value is not verified, allowing it to give predictable random values when the call to the gnutls_rnd function fails. • https://bugzilla.samba.org/show_bug.cgi?id=15103 https://gitlab.com/samba-team/samba/-/merge_requests/2644 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZTTOLTHUHOV4SHCHCB5TAA4FQVJAWN4P https://security.gentoo.org/glsa/202309-06 https://access.redhat.com/security/cve/CVE-2022-1615 https://bugzilla.redhat.com/show_bug.cgi?id=2122649 • CWE-330: Use of Insufficiently Random Values •

CVE-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 •
