CVE-2020-11100 – haproxy: malformed HTTP/2 requests can lead to out-of-bounds writes
https://notcve.org/view.php?id=CVE-2020-11100
In hpack_dht_insert in hpack-tbl.c in the HPACK decoder in HAProxy 1.8 through 2.x before 2.1.4, a remote attacker can write arbitrary bytes around a certain location on the heap via a crafted HTTP/2 request, possibly causing remote code execution. En la función hpack_dht_insert en el archivo hpack-tbl.c en el decodificador HPACK en HAProxy versiones 1.8 hasta 2.x anteriores a 2.1.4, un atacante remoto puede escribir bytes arbitrarios alrededor de una determinada ubicación en la pila (heap) por medio de una petición HTTP/2 diseñada, causando posiblemente una ejecución de código remoto. A flaw was found in the way HAProxy processed certain HTTP/2 request packets. This flaw allows an attacker to send crafted HTTP/2 request packets, which cause memory corruption, leading to a crash or potential remote arbitrary code execution with the permissions of the user running HAProxy. The haproxy hpack implementation in hpack-tbl.c handles 0-length HTTP headers incorrectly. • http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00002.html http://packetstormsecurity.com/files/157323/haproxy-hpack-tbl.c-Out-Of-Bounds-Write.html http://www.haproxy.org https://bugzilla.redhat.com/show_bug.cgi?id=1819111 https://bugzilla.suse.com/show_bug.cgi?id=1168023 https://git.haproxy.org/?p=haproxy.git%3Ba=commit%3Bh=5dfc5d5cd0d2128d77253ead3acf03a421ab5b88 https://lists.debian.org/debian-security-announce/2020/msg00052.html https://lists.fedoraproject.org/archives/list/packag • CWE-787: Out-of-bounds Write •
CVE-2020-1706 – openshift/apb-tools: /etc/passwd is given incorrect privileges
https://notcve.org/view.php?id=CVE-2020-1706
It has been found that in openshift-enterprise version 3.11 and openshift-enterprise versions 4.1 up to, including 4.3, multiple containers modify the permissions of /etc/passwd to make them modifiable by users other than root. An attacker with access to the running container can exploit this to modify /etc/passwd to add a user and escalate their privileges. This CVE is specific to the openshift/apb-tools-container. Se ha encontrado que en openshift-enterprise versión 3.11 y openshift-enterprise versiones 4.1 hasta 4.3 incluyéndola, múltiples contenedores modifican los permisos de /etc/passwd para que sean entonces modificables por otros usuarios diferentes de root. Un atacante con acceso al contenedor en ejecución puede explotar esto para modificar /etc/passwd para agregar un usuario y escalar sus privilegios. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1706 https://access.redhat.com/security/cve/CVE-2020-1706 https://bugzilla.redhat.com/show_bug.cgi?id=1793302 https://access.redhat.com/articles/4859371 • CWE-732: Incorrect Permission Assignment for Critical Resource •
CVE-2020-8945 – proglottis/gpgme: Use-after-free in GPGME bindings during container image pull
https://notcve.org/view.php?id=CVE-2020-8945
The proglottis Go wrapper before 0.1.1 for the GPGME library has a use-after-free, as demonstrated by use for container image pulls by Docker or CRI-O. This leads to a crash or potential code execution during GPG signature verification. El contenedor Proglottis Go versiones anteriores a 0.1.1 para la biblioteca GPGME, presenta un uso de la memoria previamente liberada, como es demostrado por el uso para las extracciones de imágenes de contenedores para Docker o CRI-O. Esto conlleva a un bloqueo o posible ejecución de código durante una comprobación de la firma GPG. A use-after-free vulnerability was found in the Go GPGME wrapper library, github.com/proglottis/gpgme. • https://access.redhat.com/errata/RHSA-2020:0679 https://access.redhat.com/errata/RHSA-2020:0689 https://access.redhat.com/errata/RHSA-2020:0697 https://bugzilla.redhat.com/show_bug.cgi?id=1795838 https://github.com/containers/image/commit/4c7a23f82ef09127b0ff28366d1cf31316dd6cc1 https://github.com/proglottis/gpgme/compare/v0.1.0...v0.1.1 https://github.com/proglottis/gpgme/pull/23 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3SOCLOPTSYABTE4CLTSPDIF • CWE-416: Use After Free •
