CVE-2017-3136 – An error handling synthesized records could cause an assertion failure when using DNS64 with "break-dnssec yes;"
https://notcve.org/view.php?id=CVE-2017-3136
A query with a specific set of characteristics could cause a server using DNS64 to encounter an assertion failure and terminate. An attacker could deliberately construct a query, enabling denial-of-service against a server if it was configured to use the DNS64 feature and other preconditions were met. Affects BIND 9.8.0 -> 9.8.8-P1, 9.9.0 -> 9.9.9-P6, 9.9.10b1->9.9.10rc1, 9.10.0 -> 9.10.4-P6, 9.10.5b1->9.10.5rc1, 9.11.0 -> 9.11.0-P3, 9.11.1b1->9.11.1rc1, 9.9.3-S1 -> 9.9.9-S8. Una consulta con un conjunto determinado de características podría provocar que un servidor que emplea DNS64 se encuentre con un fallo de aserción y termine. Un atacante podría construir deliberadamente una consulta, habilitando una denegación de servicio (DoS) contra un servidor si está configurado para emplear la característica DNS64 y se cumplen otras precondiciones. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00044.html http://www.securityfocus.com/bid/97653 http://www.securitytracker.com/id/1038259 https://access.redhat.com/errata/RHSA-2017:1095 https://access.redhat.com/errata/RHSA-2017:1105 https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03747en_us https://kb.isc.org/docs/aa-01465 https://security.gentoo. • CWE-617: Reachable Assertion •
CVE-2017-3137 – A response packet can cause a resolver to terminate when processing an answer containing a CNAME or DNAME
https://notcve.org/view.php?id=CVE-2017-3137
Mistaken assumptions about the ordering of records in the answer section of a response containing CNAME or DNAME resource records could lead to a situation in which named would exit with an assertion failure when processing a response in which records occurred in an unusual order. Affects BIND 9.9.9-P6, 9.9.10b1->9.9.10rc1, 9.10.4-P6, 9.10.5b1->9.10.5rc1, 9.11.0-P3, 9.11.1b1->9.11.1rc1, and 9.9.9-S8. Las asunciones equivocadas sobre el orden de los registros en la sección de respuesta de una respuesta que contiene registros de recursos CNAME o DNAME podría conducir a una situación en la que named se cerraría con un fallo de aserción al procesar una respuesta en la que los registros ocurrieron en un orden inusual. Afecta a BIND en versiones 9.9.9-P6, desde la versión 9.9.10b1 hasta la 9.9.10rc1, la versión 9.10.4-P6, desde la versión 9.10.5b1 hasta la 9.10.5rc1, la versión 9.11.0-P3, desde la versión 9.11.1b1 hasta la 9.11.1rc1 y en la versión 9.9.9-S8. A denial of service flaw was found in the way BIND handled a query response containing CNAME or DNAME resource records in an unusual order. • http://www.securityfocus.com/bid/97651 http://www.securitytracker.com/id/1038258 http://www.securitytracker.com/id/1040195 https://access.redhat.com/errata/RHSA-2017:1095 https://access.redhat.com/errata/RHSA-2017:1105 https://access.redhat.com/errata/RHSA-2017:1582 https://access.redhat.com/errata/RHSA-2017:1583 https://kb.isc.org/docs/aa-01466 https://security.gentoo.org/glsa/201708-01 https://security.netapp.com/advisory/ntap-20180802-0002 https://www.debian.org& • CWE-617: Reachable Assertion •
CVE-2018-1000001 – glibc - 'realpath()' Privilege Escalation
https://notcve.org/view.php?id=CVE-2018-1000001
In glibc 2.26 and earlier there is confusion in the usage of getcwd() by realpath() which can be used to write before the destination buffer leading to a buffer underflow and potential code execution. En glibc 2.26 y anteriores existe una confusión en el uso de getcwd() por realpath(), que puede emplearse para escribir antes del búfer de destino. Esto conduce a un subdesbordamiento de búfer y a una potencial ejecución de código. glibc suffers from a getcwd() local privilege escalation vulnerability. • https://www.exploit-db.com/exploits/44889 https://www.exploit-db.com/exploits/43775 https://github.com/0x00-0x00/CVE-2018-1000001 https://github.com/usernameid0/tools-for-CVE-2018-1000001 http://seclists.org/oss-sec/2018/q1/38 http://www.securityfocus.com/bid/102525 http://www.securitytracker.com/id/1040162 https://access.redhat.com/errata/RHSA-2018:0805 https://security.netapp.com/advisory/ntap-20190404-0003 https://usn.ubuntu.com/3534-1 https://usn.ubuntu.com • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2017-15129 – kernel: net: double-free and memory corruption in get_net_ns_by_id()
https://notcve.org/view.php?id=CVE-2017-15129
A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely. Se ha descubierto una vulnerabilidad en los nombres de espacio de red que afecta al kernel de Linux en versiones anteriores a la 4.14.11. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=21b5944350052d2583e82dd59b19a9ba94a007f0 http://seclists.org/oss-sec/2018/q1/7 http://www.securityfocus.com/bid/102485 https://access.redhat.com/errata/RHSA-2018:0654 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2019:1946 https://access.redhat.com/security/cve/CVE-2017-15129 https://bugzilla.redhat.com/show_bug.cgi& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2017-1000407 – Kernel: KVM: DoS via write flood to I/O port 0x80
https://notcve.org/view.php?id=CVE-2017-1000407
The Linux Kernel 2.6.32 and later are affected by a denial of service, by flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic. El kernel de Linux en versiones 2.6.32 y posteriores se ha visto afectado por una denegación de servicio (DoS): al inundar el puerto de diagnóstico 0x80 puede ocurrir una excepción que conduce a una situación de pánico del kernel. Linux kernel Virtualization Module (CONFIG_KVM) for the Intel processor family (CONFIG_KVM_INTEL) is vulnerable to a DoS issue. It could occur if a guest was to flood the I/O port 0x80 with write requests. A guest user could use this flaw to crash the host kernel resulting in DoS. • http://www.openwall.com/lists/oss-security/2017/12/04/2 http://www.securityfocus.com/bid/102038 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2019:1170 https://access.redhat.com/security/cve/cve-2017-1000407 https://lists.debian.org/debian-lts-announce/2017/12/msg00004.html https://usn.ubuntu.com/3583-1 https://usn.ubuntu.com/3583-2 https://usn.ubuntu.com/3617-1 https • CWE-248: Uncaught Exception CWE-754: Improper Check for Unusual or Exceptional Conditions •
