arch/mips/net/bpf_jit.c in the Linux kernel before 5.4.10 can generate undesirable machine code when transforming unprivileged cBPF programs, allowing execution of arbitrary code within the kernel context. This occurs because conditional branches can exceed the 128 KB limit of the MIPS architecture. arch/mips/net/bpf_jit.c en el kernel de Linux anterior a la versión 5.4.10 puede generar código máquina no deseado al transformar programas cBPF sin privilegios, permitiendo la ejecución de código arbitrario dentro del contexto del kernel. Esto ocurre porque las ramas condicionales pueden superar el límite de 128 KB de la arquitectura MIPS • http://www.openwall.com/lists/oss-security/2021/09/15/5 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.14.10 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=37cb28ec7d3a36a5bace7063a3dba633ab110f8b https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://security.netapp.com/advisory/ntap-20211008-0003 https://www.debian.org/security/2022/dsa-5096 •

loop_rw_iter in fs/io_uring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain privileges by using IORING_OP_PROVIDE_BUFFERS to trigger a free of a kernel buffer, as demonstrated by using /proc/<pid>/maps for exploitation. La función loop_rw_iter en fs/io_uring.c en el kernel de Linux desde la versión 5.10 hasta la versión 5.14.6 permite a los usuarios locales ganar privilegios mediante el uso de IORING_OP_PROVIDE_BUFFERS para desencadenar una liberación de un búfer del kernel, como se ha demostrado utilizando /proc//maps para su explotación • http://www.openwall.com/lists/oss-security/2021/09/18/2 http://www.openwall.com/lists/oss-security/2022/06/04/4 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=16c8d2df7ec0eed31b7d3b61cb13206a7fb930cc https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J7KSMIOQ4377CVTHMWNGNCWHMCRFRP2T https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PAP4TXEZ7J4EZQMQW5SIJMWXG7WZT3F7 https://security.netapp.com/advisory/nta • CWE-763: Release of Invalid Pointer or Reference •

A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier. Un uri-path diseñado puede causar que mod_proxy reenvíe la petición a un servidor de origen elegido por el usuario remoto. Este problema afecta a Apache HTTP Server versiones 2.4.48 y anteriores A Server-Side Request Forgery (SSRF) flaw was found in mod_proxy of httpd. This flaw allows a remote, unauthenticated attacker to make the httpd server forward requests to an arbitrary server. • https://github.com/sixpacksecurity/CVE-2021-40438 https://github.com/xiaojiangxl/CVE-2021-40438 https://github.com/Kashkovsky/CVE-2021-40438 https://github.com/sergiovks/CVE-2021-40438-Apache-2.4.48-SSRF-exploit https://github.com/BabyTeam1024/CVE-2021-40438 https://github.com/gassara-kys/CVE-2021-40438 https://github.com/Cappricio-Securities/CVE-2021-40438 https://github.com/pisut4152/Sigma-Rule-for-CVE-2021-40438-exploitation-attempt https://cert-portal.siemens.com/productcert/pdf/ • CWE-918: Server-Side Request Forgery (SSRF) •

ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache HTTP Server 2.4.48 and earlier. la función ap_escape_quotes() puede escribir más allá del final de un buffer cuando se le da una entrada maliciosa. Ningún módulo incluido pasa datos no confiables a estas funciones, pero los módulos externos o de terceros pueden hacerlo. Este problema afecta a Apache HTTP Server versiones 2.4.48 y anteriores An out-of-bounds write in function ap_escape_quotes of httpd allows an unauthenticated remote attacker to crash the server or potentially execute code on the system with the privileges of the httpd user, by providing malicious input to the function. • https://cert-portal.siemens.com/productcert/pdf/ssa-685781.pdf https://httpd.apache.org/security/vulnerabilities_24.html 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/r82838efc5fa6fc4c73986399c9b71573589f78b31846aff5bd9b1697%40%3Cusers.httpd.apache.org%3E https://lists.apache.org/thread.html/r82c077663f9759c7df5a6656f925b3ee4f55fc • CWE-787: Out-of-bounds Write •

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 •
