A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c. This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space En el archivo net/netfilter/x_tables.c se ha detectado una escritura fuera de límites en la pila que afecta a Linux desde la versión 2.6.19-rc1. Esto permite a un atacante alcanzar privilegios o causar una denegación de servicio (por medio de corrupción de la memoria de la pila) mediante el espacio de nombres de usuario A flaw was discovered in processing setsockopt IPT_SO_SET_REPLACE (or IP6T_SO_SET_REPLACE) for 32 bit processes on 64 bit systems. This flaw will allow local user to gain privileges or cause a DoS through user name space. This action is usually restricted to root-privileged users but can also be leveraged if the kernel is compiled with CONFIG_USER_NS and CONFIG_NET_NS and the user is granted elevated privileges. • https://www.exploit-db.com/exploits/50135 https://github.com/xyjl-ly/CVE-2021-22555-Exploit https://github.com/veritas501/CVE-2021-22555-PipeVersion https://github.com/pashayogi/CVE-2021-22555 https://github.com/tukru/CVE-2021-22555 https://github.com/letsr00t/CVE-2021-22555 https://github.com/letsr00t/-2021-LOCALROOT-CVE-2021-22555 https://github.com/daletoniris/CVE-2021-22555-esc-priv http://packetstormsecurity.com/files/163528/Linux-Kernel-Netfilter-Heap-Out-Of-Bounds-Write.h • CWE-787: Out-of-bounds Write •

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 •

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 •
