CVE-2022-45141
https://notcve.org/view.php?id=CVE-2022-45141
Since the Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability was disclosed by Microsoft on Nov 8 2022 and per RFC8429 it is assumed that rc4-hmac is weak, Vulnerable Samba Active Directory DCs will issue rc4-hmac encrypted tickets despite the target server supporting better encryption (eg aes256-cts-hmac-sha1-96). Dado que la vulnerabilidad de elevación de privilegios de Windows Kerberos RC4-HMAC fue revelada por Microsoft el 8 de noviembre de 2022 y según RFC8429 se asume que rc4-hmac es débil, los DC de Directorio Activo Samba vulnerables emitirán tickets cifrados rc4-hmac a pesar de que el servidor de destino admita un cifrado mejor (por ejemplo, aes256-cts-hmac-sha1-96). • https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2022-45141.html • CWE-326: Inadequate Encryption Strength CWE-328: Use of Weak Hash •
CVE-2022-44640
https://notcve.org/view.php?id=CVE-2022-44640
Heimdal before 7.7.1 allows remote attackers to execute arbitrary code because of an invalid free in the ASN.1 codec used by the Key Distribution Center (KDC). Heimdal anterior a 7.7.1 permite a atacantes remotos ejecutar código arbitrario debido a un free no válido en el códec ASN.1 utilizado por el Centro de distribución de claves (KDC). • https://github.com/heimdal/heimdal/security/advisories/GHSA-88pm-hfmq-7vv4 https://security.gentoo.org/glsa/202310-06 https://security.netapp.com/advisory/ntap-20230216-0008 •
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 •
