CVE-2019-14833
https://notcve.org/view.php?id=CVE-2019-14833
A flaw was found in Samba, all versions starting samba 4.5.0 before samba 4.9.15, samba 4.10.10, samba 4.11.2, in the way it handles a user password change or a new password for a samba user. The Samba Active Directory Domain Controller can be configured to use a custom script to check for password complexity. This configuration can fail to verify password complexity when non-ASCII characters are used in the password, which could lead to weak passwords being set for samba users, making it vulnerable to dictionary attacks. Se encontró un fallo en Samba, todas las versiones iniciando samba versiones 4.5.0 anteriores a samba 4.9.15, samba versión 4.10.10, samba versión 4.11.2, en la manera en que maneja un cambio de contraseña de usuario o una nueva contraseña para un usuario de samba. El Controlador de Dominio Active Directory de Samba puede ser configurado para usar un script personalizado para comprobar la complejidad de la contraseña. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00015.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14833 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.debian.org/debian-lts-announce/2023/09/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OKPYHDFI7HRELVXBE5J4MTGSI35AKFBI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UMIYCYXCPRTVCVZ3TP6ZGPJ6RZS3IX4G https: • CWE-305: Authentication Bypass by Primary Weakness CWE-521: Weak Password Requirements •
CVE-2019-17596 – golang: invalid public key causes panic in dsa.Verify
https://notcve.org/view.php?id=CVE-2019-17596
Go before 1.12.11 and 1.3.x before 1.13.2 can panic upon an attempt to process network traffic containing an invalid DSA public key. There are several attack scenarios, such as traffic from a client to a server that verifies client certificates. Go versiones anteriores a 1.12.11 y versiones 1.3.x anteriores a 1.13.2, puede entrar en pánico tras intentar procesar el tráfico de red que contiene una clave pública DSA no válida. Existen varios escenarios de ataque, tal y como el tráfico de un cliente hacia un servidor que comprueba los certificados del cliente. • https://github.com/pquerna/poc-dsa-verify-CVE-2019-17596 http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00043.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00044.html https://access.redhat.com/errata/RHSA-2020:0101 https://access.redhat.com/errata/RHSA-2020:0329 https://github.com/golang/go/issues/34960 https://groups.google.com/d/msg/golang-announce/lVEm7llp0w0/VbafyRkgCgAJ https://lists.debian.org/debian-lts-announce/2021/03/msg00014.html https& • CWE-295: Improper Certificate Validation CWE-436: Interpretation Conflict •

CVE-2019-18218 – file: heap-based buffer overflow in cdf_read_property_info in cdf.c
https://notcve.org/view.php?id=CVE-2019-18218
cdf_read_property_info in cdf.c in file through 5.37 does not restrict the number of CDF_VECTOR elements, which allows a heap-based buffer overflow (4-byte out-of-bounds write). La función cdf_read_property_info en el archivo cdf.c en file versiones hasta 5.37, no restringe el número de elementos CDF_VECTOR, lo que permite un desbordamiento del búfer en la región heap de la memoria (escritura fuera de límites de 4 bytes). • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00044.html https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=16780 https://github.com/file/file/commit/46a8443f76cec4b41ec736eca396984c74664f84 https://lists.debian.org/debian-lts-announce/2019/10/msg00032.html https://lists.debian.org/debian-lts-announce/2021/07/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CV6PFCEYHYALMTT45QE2U5C5TEJZQPXJ https://lists.fedoraproject.org/archives/list/p • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2019-17498 – libssh2: integer overflow in SSH_MSG_DISCONNECT logic in packet.c
https://notcve.org/view.php?id=CVE-2019-17498
In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent memory read. A crafted SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server. En libssh2 versión v1.9.0 y anteriores, la lógica de la función SSH_MSG_DISCONNECT en el archivo packet.c presenta un desbordamiento de enteros en una comprobación de límites, lo que permite a un atacante especificar un desplazamiento arbitrario (fuera de límites) para una lectura de memoria posterior. Un servidor SSH diseñado puede ser capaz de revelar información confidencial o causar una condición de denegación de servicio en el sistema del cliente cuando un usuario conecta con el servidor. libssh2 version 1.9.0 contains a remotely trigger-able out-of-bounds read, leading to denial of service or potentially to information disclosure. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00026.html http://packetstormsecurity.com/files/172835/libssh2-1.9.0-Out-Of-Bounds-Read.html https://blog.semmle.com/libssh2-integer-overflow-CVE-2019-17498 https://github.com/kevinbackhouse/SecurityExploits/tree/8cbdbbe6363510f7d9ceec685373da12e6fc752d/libssh2/out_of_bounds_read_disconnect_CVE-2019-17498 https://github.com/libssh2/libssh2/blob/42d37aa63129a1b2644bf6495198923534322d64/src/packet.c#L480 https://github.com/libssh2/libssh2/commit/dedcbd106f8e52d5586b0205bc7677e4c • CWE-190: Integer Overflow or Wraparound CWE-400: Uncontrolled Resource Consumption •
