CVE-2018-12121 – nodejs: Denial of Service with large HTTP headers
https://notcve.org/view.php?id=CVE-2018-12121
Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Denial of Service with large HTTP headers: By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer. Node.js: Todas las versiones anteriores a la 6.15.0, 8.14.0, 10.14.0 y 11.3.0: Denegación de servicio (DoS) con cabeceras HTTP grandes. Mediante la combinación de muchas peticiones con cabeceras de tamaño máximo (casi 80 KB por conexión) y al terminar a su debido tiempo las cabeceras, es posible provocar que el servidor HTTP aborte el fallo de asignación de memoria dinámica (heap). El potencial del ataque se ve mitigado por el uso de un balance de carga u otra capa del proxy. • http://www.securityfocus.com/bid/106043 https://access.redhat.com/errata/RHSA-2019:1821 https://access.redhat.com/errata/RHSA-2019:2258 https://access.redhat.com/errata/RHSA-2019:3497 https://nodejs.org/en/blog/vulnerability/november-2018-security-releases https://security.gentoo.org/glsa/202003-48 https://access.redhat.com/security/cve/CVE-2018-12121 https://bugzilla.redhat.com/show_bug.cgi?id=1661002 • CWE-400: Uncontrolled Resource Consumption •
CVE-2018-14646 – kernel: NULL pointer dereference in af_netlink.c:__netlink_ns_capable() allows for denial of service
https://notcve.org/view.php?id=CVE-2018-14646
The Linux kernel before 4.15-rc8 was found to be vulnerable to a NULL pointer dereference bug in the __netlink_ns_capable() function in the net/netlink/af_netlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service. El kernel de Linux en versiones anteriores a la 4.15-rc8 era vulnerable a un error de desreferencia de puntero NULL en la función __netlink_ns_capable() en el archivo net/netlink/af_netlink.c. Un atacante local podría explotarlo cuando un espacio de nombres de red con un netnsid se asigne para provocar un kernel de pánico y ataque de denegación de servicio (DoS). The Linux kernel was found to be vulnerable to a NULL pointer dereference bug in the __netlink_ns_capable() function in the net/netlink/af_netlink.c file. • https://access.redhat.com/errata/RHSA-2018:3651 https://access.redhat.com/errata/RHSA-2018:3666 https://access.redhat.com/errata/RHSA-2018:3843 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14646 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f428fe4a04cc339166c8bbd489789760de3a0cee https://marc.info/?l=linux-netdev&m=151500466401174&w=2 https://access.redhat.com/security/cve/CVE-2018-14646 https://bugzilla.redhat.com/show_bug.cgi?id=1630124 • CWE-476: NULL Pointer Dereference •
CVE-2018-19535 – exiv2: heap-based buffer over-read in PngChunk::readRawProfile in pngchunk_int.cpp
https://notcve.org/view.php?id=CVE-2018-19535
In Exiv2 0.26 and previous versions, PngChunk::readRawProfile in pngchunk_int.cpp may cause a denial of service (application crash due to a heap-based buffer over-read) via a crafted PNG file. En la versión 0.26 de Exiv2 y en versiones anteriores, PngChunk::readRawProfile en pngchunk_int.cpp podría provocar un ataque de denegación de servicio (cierre inesperado de la aplicación debido a una sobrelectura de búfer basada en memoria dinámica o heap) mediante un archivo PNG manipulado. • https://access.redhat.com/errata/RHSA-2019:2101 https://github.com/Exiv2/exiv2/issues/428 https://github.com/Exiv2/exiv2/pull/430 https://lists.debian.org/debian-lts-announce/2019/02/msg00038.html https://lists.debian.org/debian-lts-announce/2023/01/msg00004.html https://usn.ubuntu.com/4056-1 https://access.redhat.com/security/cve/CVE-2018-19535 https://bugzilla.redhat.com/show_bug.cgi?id=1656187 • CWE-125: Out-of-bounds Read •
