CVE-2020-13529 – systemd: DHCP FORCERENEW authentication not implemented can cause a system running the DHCP client to have its network reconfigured
https://notcve.org/view.php?id=CVE-2020-13529
An exploitable denial-of-service vulnerability exists in Systemd 245. A specially crafted DHCP FORCERENEW packet can cause a server running the DHCP client to be vulnerable to a DHCP ACK spoofing attack. An attacker can forge a pair of FORCERENEW and DCHP ACK packets to reconfigure the server. Se presenta una vulnerabilidad de denegación de servicio explotable en Systemd 245. Un paquete DHCP FORCERENEW especialmente diseñado puede hacer que un servidor que ejecuta el cliente DHCP sea vulnerable a un ataque de suplantación de DHCP ACK. • http://www.openwall.com/lists/oss-security/2021/08/04/2 http://www.openwall.com/lists/oss-security/2021/08/17/3 http://www.openwall.com/lists/oss-security/2021/09/07/3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/42TMJVNYRY65B4QCJICBYOEIVZV3KUYI https://security.gentoo.org/glsa/202107-48 https://security.netapp.com/advisory/ntap-20210625-0005 https://talosintelligence.com/vulnerability_reports/TALOS-2020-1142 https://access.redhat.com/securit • CWE-290: Authentication Bypass by Spoofing CWE-306: Missing Authentication for Critical Function •
CVE-2021-25216 – A second vulnerability in BIND's GSSAPI security policy negotiation can be targeted by a buffer overflow attack
https://notcve.org/view.php?id=CVE-2021-25216
In BIND 9.5.0 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.11.3-S1 -> 9.11.29-S1 and 9.16.8-S1 -> 9.16.13-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch, BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting values for the tkey-gssapi-keytab or tkey-gssapi-credential configuration options. Although the default configuration is not vulnerable, GSS-TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server environments that combine BIND servers with Active Directory domain controllers. For servers that meet these conditions, the ISC SPNEGO implementation is vulnerable to various attacks, depending on the CPU architecture for which BIND was built: For named binaries compiled for 64-bit platforms, this flaw can be used to trigger a buffer over-read, leading to a server crash. For named binaries compiled for 32-bit platforms, this flaw can be used to trigger a server crash due to a buffer overflow and possibly also to achieve remote code execution. • http://www.openwall.com/lists/oss-security/2021/04/29/1 http://www.openwall.com/lists/oss-security/2021/04/29/2 http://www.openwall.com/lists/oss-security/2021/04/29/3 http://www.openwall.com/lists/oss-security/2021/04/29/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://kb.isc.org/v1/docs/cve-2021-25215 https://lists.debian.org/debian-lts-announce/2021/05/msg00001.html https://security.netapp.com/advisory/ntap-20210521-0006 http • CWE-125: Out-of-bounds Read •
CVE-2021-25215 – An assertion check can fail while answering queries for DNAME records that require the DNAME to be processed to resolve itself
https://notcve.org/view.php?id=CVE-2021-25215
In BIND 9.0.0 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and 9.16.8-S1 -> 9.16.13-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11 of the BIND 9.17 development branch, when a vulnerable version of named receives a query for a record triggering the flaw described above, the named process will terminate due to a failed assertion check. The vulnerability affects all currently maintained BIND 9 branches (9.11, 9.11-S, 9.16, 9.16-S, 9.17) as well as all other versions of BIND 9. En BIND versiones 9.0.0 posteriores a 9.11.29, versiones 9.12.0 posteriores a 9.16.13, y BIND versiones 9.9.3-S1 posteriores a 9.11.29-S1 y versiones 9.16.8-S1 posteriores a 9.16.13-S1 de BIND Supported Preview Edition, así como versiones de lanzamiento 9.17.0 posteriores a 9.17.11 de la rama de desarrollo de BIND versión 9.17, cuando una versión vulnerable de named recibe una consulta para un registro que desencadena un fallo descrito anteriormente, el proceso named terminará debido a un comprobación de afirmación fallido. La vulnerabilidad afecta a todas las ramas de BIND 9 que se mantienen actualmente (9.11, 9.11-S, 9.16, 9.16-S, 9.17), así como a todas las demás versiones de BIND 9 A flaw was found in bind. The way DNAME records are processed may trigger the same RRset to the ANSWER section to be added more than once which causes an assertion check to fail. • http://www.openwall.com/lists/oss-security/2021/04/29/1 http://www.openwall.com/lists/oss-security/2021/04/29/2 http://www.openwall.com/lists/oss-security/2021/04/29/3 http://www.openwall.com/lists/oss-security/2021/04/29/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://kb.isc.org/v1/docs/cve-2021-25215 https://lists.debian.org/debian-lts-announce/2021/05/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce& • CWE-617: Reachable Assertion •
CVE-2021-25214 – A broken inbound incremental zone update (IXFR) can cause named to terminate unexpectedly
https://notcve.org/view.php?id=CVE-2021-25214
In BIND 9.8.5 -> 9.8.8, 9.9.3 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and 9.16.8-S1 -> 9.16.13-S1 of BIND 9 Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11 of the BIND 9.17 development branch, when a vulnerable version of named receives a malformed IXFR triggering the flaw described above, the named process will terminate due to a failed assertion the next time the transferred secondary zone is refreshed. En BIND versiones 9.8.5 posteriores a 9.8.8, versiones 9.9.3 posteriores a 9.11.29, versiones 9.12.0 posteriores a 9.16.13, y BIND versiones 9.9.3-S1 posteriores a 9.11.29-S1 y versiones 9.16.8-S1 posteriores a 9.16.13-S1 de BIND 9 Supported Preview Edition, así como versiones de lanzamiento 9.17.0 posteriores a 9.17.11 de la rama de desarrollo de BIND versión 9.17, cuando una versión vulnerable de named recibe un IXFR malformado que desencadena el fallo descrito anteriormente, el proceso named finalizará debido a una aserción fallida la próxima vez que se actualice la zona secundaria transferida Incremental zone transfers (IXFR) provide a way of transferring changed portion(s) of a zone between servers. An IXFR stream containing SOA records with an owner name other than the transferred zone's apex may cause the receiving named server to inadvertently remove the SOA record for the zone in question from the zone database. This leads to an assertion failure when the next SOA refresh query for that zone is made. • http://www.openwall.com/lists/oss-security/2021/04/29/1 http://www.openwall.com/lists/oss-security/2021/04/29/2 http://www.openwall.com/lists/oss-security/2021/04/29/3 http://www.openwall.com/lists/oss-security/2021/04/29/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://kb.isc.org/v1/docs/cve-2021-25214 https://lists.debian.org/debian-lts-announce/2021/05/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce& • CWE-617: Reachable Assertion •
