A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00008.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10711 https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://security.netapp.com/advisory/ntap-20200608-0001 https://usn.ubuntu.com/4411-1 https://usn.ubuntu.com/4412-1 https://usn.ubuntu.com/4413-1 https://usn.ubuntu.com/4414-1 https://usn.ubuntu& • CWE-476: NULL Pointer Dereference •

A flaw was found in the Ceph Object Gateway, where it supports request sent by an anonymous user in Amazon S3. This flaw could lead to potential XSS attacks due to the lack of proper neutralization of untrusted input. Se encontró un fallo en Ceph Object Gateway, donde admite peticiones enviadas por un usuario anónimo en Amazon S3. Este fallo podría conllevar a posibles ataques de tipo XSS debido a una falta de neutralización apropiada de una entrada no segura. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1760 https://lists.debian.org/debian-lts-announce/2021/08/msg00013.html https://lists.debian.org/debian-lts-announce/2023/10/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/P3A2UFR5IUIEXJUCF64GQ5OVLCZGODXE https://security.gentoo.org/glsa/202105-39 https://usn.ubuntu.com/4528-1 https://www.openwall.com/lists/oss-security/2020/04/07/1 https://access.redhat.com/security/cve/ • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

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 •

A heap use-after-free vulnerability was found in systemd before version v245-rc1, where asynchronous Polkit queries are performed while handling dbus messages. A local unprivileged attacker can abuse this flaw to crash systemd services or potentially execute code and elevate their privileges, by sending specially crafted dbus messages. Se detectó una vulnerabilidad uso de la memoria previamente liberada de la pila en systemd versiones anteriores a v245-rc1, donde se llevaron a cabo consultas de Polkit asincrónicas mientras se manejan mensajes dbus. Un atacante no privilegiado local puede abusar de este fallo para bloquear los servicios de systemd o potencialmente ejecutar código y elevar sus privilegios, mediante el envío de mensajes dbus especialmente diseñados.
