https://notcve.org/view.php?id=CVE-2020-10772
An incomplete fix for CVE-2020-12662 was shipped for Unbound in Red Hat Enterprise Linux 7, as part of erratum RHSA-2020:2414. Vulnerable versions of Unbound could still amplify an incoming query into a large number of queries directed to a target, even with a lower amplification ratio compared to versions of Unbound that shipped before the mentioned erratum. This issue is about the incomplete fix for CVE-2020-12662, and it does not affect upstream versions of Unbound. Una corrección incompleta fue entregada para CVE-2020-12662 para Unbound en Red Hat Enterprise Linux versión 7, como parte de la errata de RHSA-2020: 2414. Las versiones vulnerables de Unbound aún podrían amplificar una consulta entrante en una gran cantidad de consultas dirigidas a un objetivo, inclusive con un índice de amplificación más bajo en comparación con las versiones de Unbound que se enviaron antes de la errata mencionada. • https://bugzilla.redhat.com/show_bug.cgi?id=1846026 https://access.redhat.com/security/cve/CVE-2020-10772 • CWE-400: Uncontrolled Resource Consumption CWE-406: Insufficient Control of Network Message Volume (Network Amplification) •
CVE-2020-12826 – kernel: possible to send arbitrary signals to a privileged (suidroot) parent process
https://notcve.org/view.php?id=CVE-2020-12826
A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2. Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial operational threat. Se detectó un problema de control de acceso de señal en el kernel de Linux versiones anteriores a 5.6.5, se conoce como CID-7395ea4e65c2. • https://bugzilla.redhat.com/show_bug.cgi?id=1822077 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.6.5 https://github.com/torvalds/linux/commit/7395ea4e65c2a00d23185a3f63ad315756ba9cef https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://lists.openwall.net/linux-kernel/2020/03/24/1803 https://security.netapp.com/advisory/ntap-20200608-0001 https://usn.ubuntu.com/4367-1 https://u • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-190: Integer Overflow or Wraparound •

CVE-2019-19906 – cyrus-sasl: denial of service in _sasl_add_string function
https://notcve.org/view.php?id=CVE-2019-19906
cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl. cyrus-sasl (también se conoce como Cyrus SASL) versión 2.1.27, presenta una escritura fuera de límites conllevando a una denegación de servicio remota no autenticada en OpenLDAP por medio de un paquete LDAP malformado. El bloqueo de OpenLDAP es causado en última instancia por un error por un paso en la función _sasl_add_string en el archivo common.c en cyrus-sasl. • http://seclists.org/fulldisclosure/2020/Jul/23 http://seclists.org/fulldisclosure/2020/Jul/24 http://www.openwall.com/lists/oss-security/2022/02/23/4 https://github.com/cyrusimap/cyrus-sasl/issues/587 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts-announce/2019/12/msg00027.h • CWE-193: Off-by-one Error CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •
