https://notcve.org/view.php?id=CVE-2021-36160
A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive). Una uri-path de petición cuidadosamente diseñada puede causar que la función mod_proxy_uwsgi lea por encima de la memoria asignada y se bloquee (DoS). Este problema afecta a Apache HTTP Server versiones 2.4.30 a 2.4.48 (incluyéndola) An out-of-bounds read in mod_proxy_uwsgi of httpd allows a remote unauthenticated attacker to crash the service through a crafted request. The highest threat from this vulnerability is to system availability. • http://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/r2eb200ac1340f69aa22af61ab34780c531d110437910cb9c0ece3b37%40%3Cbugs.httpd.apache.org%3E https://lists.apache.org/thread.html/r3925e167d5eb1c75def3750c155d753064e1d34a143028bb32910432%40%3Cusers.httpd.apache.org%3E https://lists.apache.org/thread.html/r61fdbfc26ab170f4e6492ef3bd5197c20b862ce156e9d5a54d4b899c%40%3Cusers.httpd.apache.org%3E https://lists.apache.org/thread.html/r73260f6ba9fb52e43d860905fc90462ba5a814afda2d011f32bbd41c%40%3Cbugs.httpd.apache.org%3E https://lists.apache • CWE-125: Out-of-bounds Read •

Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier. Unas peticiones malformadas pueden causar que el servidor haga desreferencia a un puntero NULL.

CVSS: 7.0EPSS: 0%CPEs: 30EXPL: 1CVE-2021-23133 – Linux Kernel sctp_destroy_sock race condition
https://notcve.org/view.php?id=CVE-2021-23133
A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. Una condición de carrera en los sockets SCTP del kernel de Linux (el archivo net/sctp/socket.c) versiones anteriores a 5.12-rc8, puede conllevar a una escalada de privilegios del kernel desde el contexto de un servicio de red o un proceso no privilegiado. Si la función sctp_destroy_sock es llamado sin sock_net (sk) -) sctp.addr_wq_lock, un elemento es eliminado de la lista auto_asconf_splist sin ningún bloqueo apropiado. • http://www.openwall.com/lists/oss-security/2021/05/10/1 http://www.openwall.com/lists/oss-security/2021/05/10/2 http://www.openwall.com/lists/oss-security/2021/05/10/3 http://www.openwall.com/lists/oss-security/2021/05/10/4 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b166a20b07382b8bc1dcee2a448715c9c2c81b5b https://lists.debian.org/debian-lts-announce/2021/06/msg00019.html https://lists.debian.org/debian-lts-announce/2021/06/msg000 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2021-20197
There is an open race window when writing output in the following utilities in GNU binutils version 2.35 and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as part of a script updating binaries across different users), an unprivileged user can trick these utilities into getting ownership of arbitrary files through a symlink. Se presenta una ventana de carrera abierta cuando se escribe la salida en las siguientes utilidades en GNU binutils versiones 2.35 y anteriores: ar, objcopy, strip, ranlib. Cuando estas utilidades son ejecutadas como un usuario privilegiado (presumiblemente como parte de un script que actualiza binarios entre diferentes usuarios), un usuario sin privilegios puede engañar a estas utilidades para que obtengan la propiedad de archivos arbitrario por medio de un enlace simbólico. There is an open race window when writing output in the following utilities in GNU binutils1: ar, objcopy, strip, and ranlib. • https://bugzilla.redhat.com/show_bug.cgi?id=1913743 https://security.gentoo.org/glsa/202208-30 https://security.netapp.com/advisory/ntap-20210528-0009 https://sourceware.org/bugzilla/show_bug.cgi?id=26945 https://access.redhat.com/security/cve/CVE-2021-20197 • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
