In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory). En Expat (también se conoce como libexpat) versiones anteriores a 2.4.3, un desplazamiento a la izquierda por 29 (o más) lugares en la función storeAtts en el archivo xmlparse.c puede conllevar a un comportamiento incorrecto de reasignación (por ejemplo, asignar muy pocos bytes, o sólo liberar memoria). expat (libexpat) is susceptible to a software flaw that causes process interruption. When processing a large number of prefixed XML attributes on a single tag can libexpat can terminate unexpectedly due to buffer overrun. The highest threat from this vulnerability is to availability. • http://www.openwall.com/lists/oss-security/2022/01/17/3 https://bugzilla.mozilla.org/show_bug.cgi?id=1217609 https://cert-portal.siemens.com/productcert/pdf/ssa-484086.pdf https://github.com/libexpat/libexpat/issues/531 https://github.com/libexpat/libexpat/pull/534 https://security.gentoo.org/glsa/202209-24 https://security.netapp.com/advisory/ntap-20220121-0004 https://www.debian.org/security/2022/dsa-5073 https://www.tenable.com/security/tns-2022-05 https://acces • CWE-130: Improper Handling of Length Parameter Inconsistency CWE-682: Incorrect Calculation •

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) •

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. Este problema afecta a Apache HTTP Server versiones 2.4.48 y anteriores A NULL pointer dereference in httpd allows an unauthenticated remote attacker to crash httpd by providing malformed HTTP requests.
