In Wireshark 3.2.0 to 3.2.3, 3.0.0 to 3.0.10, and 2.6.0 to 2.6.16, the NFS dissector could crash. This was addressed in epan/dissectors/packet-nfs.c by preventing excessive recursion, such as for a cycle in the directory graph on a filesystem. En Wireshark versiones 3.2.0 hasta 3.2.3, 3.0.0 hasta 3.0.10 y 2.6.0 hasta 2.6.16, el disector NFS podría bloquearse. Esto se abordó en el archivo epan/dissectors/packet-nfs.c impidiendo la recurrencia excesiva, como por ejemplo, un ciclo en el gráfico de directorio en un sistema de archivos. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00038.html https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=16476 https://code.wireshark.org/review/gitweb?p=wireshark.git%3Ba=commit%3Bh=e6e98eab8e5e0bbc982cfdc808f2469d7cab6c5a https://lists.debian.org/debian-lts-announce/2021/02/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5UOISPQTRCZGQLKBVXEDL72AEXEHS425 https://lists • CWE-674: Uncontrolled Recursion •
CVE-2020-10723 – dpdk: librte_vhost Integer truncation in vhost_user_check_and_alloc_queue_pair()
https://notcve.org/view.php?id=CVE-2020-10723
A memory corruption issue was found in DPDK versions 17.05 and above. This flaw is caused by an integer truncation on the index of a payload. Under certain circumstances, the index (a UInt) is copied and truncated into a uint16, which can lead to out of bound indexing and possible memory corruption. Se encontró un problema de corrupción de memoria en DPDK versiones 17.05 y superiores. Este fallo es causado por un truncamiento de enteros en el índice de una carga útil. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00045.html https://bugs.dpdk.org/show_bug.cgi?id=268 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10723 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HRHKFVV4MRWNNJOYQOVP64L4UVWYPEO4 https://usn.ubuntu.com/4362-1 https://www.openwall.com/lists/oss-security/2020/05/18/2 https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security-alerts/cpuoct2020 • CWE-190: Integer Overflow or Wraparound •
CVE-2020-10995
https://notcve.org/view.php?id=CVE-2020-10995
PowerDNS Recursor from 4.1.0 up to and including 4.3.0 does not sufficiently defend against amplification attacks. An issue in the DNS protocol has been found that allow malicious parties to use recursive DNS services to attack third party authoritative name servers. The attack uses a crafted reply by an authoritative name server to amplify the resulting traffic between the recursive and other authoritative name servers. Both types of service can suffer degraded performance as an effect. This is triggered by random subdomains in the NSDNAME in NS records. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00052.html http://www.nxnsattack.com https://doc.powerdns.com/recursor/security-advisories/powerdns-advisory-2020-01.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NMP72NJGKBWR5WEBXAWX5KSLQUDFTG6S https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PS4ZN5XGENYNFKX7QIIOUCQQHXE37GJF https://www.debian.org/security/2020/dsa-4691 • CWE-400: Uncontrolled Resource Consumption •
CVE-2020-8617 – A logic error in code which checks TSIG validity can be used to trigger an assertion failure in tsig.c
https://notcve.org/view.php?id=CVE-2020-8617
Using a specially-crafted message, an attacker may potentially cause a BIND server to reach an inconsistent state if the attacker knows (or successfully guesses) the name of a TSIG key used by the server. Since BIND, by default, configures a local session key even on servers whose configuration does not otherwise make use of it, almost all current BIND servers are vulnerable. In releases of BIND dating from March 2018 and after, an assertion check in tsig.c detects this inconsistent state and deliberately exits. Prior to the introduction of the check the server would continue operating in an inconsistent state, with potentially harmful results. Al usar un mensaje especialmente diseñado, un atacante puede causar que un servidor BIND alcance un estado inconsistente si el atacante conoce (o adivina con éxito) el nombre de una clave TSIG utilizada por el servidor. • https://www.exploit-db.com/exploits/48521 https://github.com/knqyf263/CVE-2020-8617 http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00044.html http://packetstormsecurity.com/files/157836/BIND-TSIG-Denial-Of-Service.html http://www.openwall.com/lists/oss-security/2020/05/19/4 https://kb.isc.org/docs/cve-2020-8617 https://lists.debian.org/debian-lts-announce/2020/05/msg00031.html https:/ • CWE-617: Reachable Assertion •

An issue has been found in PowerDNS Recursor 4.1.0 through 4.3.0 where records in the answer section of a NXDOMAIN response lacking an SOA were not properly validated in SyncRes::processAnswer, allowing an attacker to bypass DNSSEC validation. Se detectó un problema en PowerDNS Recursor versiones 4.1.0 hasta 4.3.0, donde los registros en la sección de respuestas de una respuesta NXDOMAIN que carece de SOA no fueron comprobados apropiadamente en las función SyncRes::processAnswer, permitiendo a un atacante omitir la comprobación DNSSEC. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00052.html http://www.openwall.com/lists/oss-security/2020/05/19/3 https://doc.powerdns.com/recursor/security-advisories/powerdns-advisory-2020-02.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NMP72NJGKBWR5WEBXAWX5KSLQUDFTG6S https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PS4ZN5XGENYNFKX7QIIOUCQQHXE37GJF https://www.debian.org/security/2020/dsa-4691 • CWE-347: Improper Verification of Cryptographic Signature •
