CVE-2018-14622
https://notcve.org/view.php?id=CVE-2018-14622
A null-pointer dereference vulnerability was found in libtirpc before version 0.3.3-rc3. The return value of makefd_xprt() was not checked in all instances, which could lead to a crash when the server exhausted the maximum number of available file descriptors. A remote attacker could cause an rpc-based application to crash by flooding it with new connections. Se ha encontrado una vulnerabilidad de desreferencia de puntero NULL en libtirpc en versiones anteriores a la 0.3.3-rc3. El valor de retorno de makefd_xprt() no se comprobó en todas las instancias, lo que podría conducir a un cierre inesperado cuando el servidor agotó el número máximo de descriptores de archivo disponibles. • http://git.linux-nfs.org/?p=steved/libtirpc.git%3Ba=commit%3Bh=1c77f7a869bdea2a34799d774460d1f9983d45f0 https://access.redhat.com/errata/RHBA-2017:1991 https://bugzilla.novell.com/show_bug.cgi?id=968175 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14622 https://lists.debian.org/debian-lts-announce/2018/08/msg00034.html https://usn.ubuntu.com/3759-1 https://usn.ubuntu.com/3759-2 • CWE-252: Unchecked Return Value •
CVE-2018-16062 – elfutils: Heap-based buffer over-read in libdw/dwarf_getaranges.c:dwarf_getaranges() via crafted file
https://notcve.org/view.php?id=CVE-2018-16062
dwarf_getaranges in dwarf_getaranges.c in libdw in elfutils before 2018-08-18 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted file. dwarf_getaranges en dwarf_getaranges.c en libdw en elfutils en versiones anteriores al 18/08/2018 permite que atacantes remotos provoquen una denegación de servicio (sobrelectura de búfer basada en memoria dinámica o heap) mediante un archivo manipulado. An out-of-bounds read was discovered in elfutils in the way it reads DWARF address ranges information. Function dwarf_getaranges() in dwarf_getaranges.c does not properly check whether it reads beyond the limits of the ELF section.

CVE-2018-5740 – A flaw in the "deny-answer-aliases" feature can cause an assertion failure in named
https://notcve.org/view.php?id=CVE-2018-5740
"deny-answer-aliases" is a little-used feature intended to help recursive server operators protect end users against DNS rebinding attacks, a potential method of circumventing the security model used by client browsers. However, a defect in this feature makes it easy, when the feature is in use, to experience an assertion failure in name.c. Affects BIND 9.7.0->9.8.8, 9.9.0->9.9.13, 9.10.0->9.10.8, 9.11.0->9.11.4, 9.12.0->9.12.2, 9.13.0->9.13.2. "deny-answer-aliases" es una característica poco utilizada que pretende ayudar a los operadores recursivos del servidor a proteger a los usuarios finales contra ataques de reenlace DNS, un método para poder eludir el modelo de seguridad empleado por los navegadores del cliente. Sin embargo, un defecto en esta característica hace que sea sencillo experimentar un fallo de aserción en name.c. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00027.html http://www.securityfocus.com/bid/105055 http://www.securitytracker.com/id/1041436 https://access.redhat.com/errata/RHSA-2018:2570 https://access.redhat.com/errata/RHSA-2018:2571 https://kb.isc.org/docs/aa-01639 https://lists.debian.org/debian-lts-announce/2018/08/msg00033.html https://lists.debian.org/debian-lts-announce/2021/11 • CWE-617: Reachable Assertion •
