In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak because the hash table is very small. En la implementación de IPv4 en el kernel de Linux versiones anteriores a 5.12.4, el archivo net/ipv4/route.c presenta un filtrado de información porque la tabla hash es muy pequeña An information leak flaw was found in the Linux kernel’s IPv4 implementation in the ip_rt_init in net/ipv4/route.c function. The use of a small hash table in IP ID generation allows a remote attacker to reveal sensitive information. • https://arxiv.org/pdf/2112.09604.pdf https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.12.4 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/net/ipv4/route.c?id=aa6dd211e4b1dde9d5dc25d699d35f789ae7eeba https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2021-45486 https://bugzilla.redhat.com/show_bug.cgi?id=2039914 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-327: Use of a Broken or Risky Cryptographic Algorithm •

Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1. Apache Log4j2 versiones 2.0-alpha1 hasta 2.16.0 (excluyendo las versiones 2.12.3 y 2.3.1) no protegían de la recursión no controlada de las búsquedas autorreferenciales. Esto permite a un atacante con control sobre los datos de Thread Context Map causar una denegación de servicio cuando es interpretada una cadena diseñada. • https://github.com/thedevappsecguy/Log4J-Mitigation-CVE-2021-44228--CVE-2021-45046--CVE-2021-45105--CVE-2021-44832 https://github.com/tejas-nagchandi/CVE-2021-45105 https://github.com/pravin-pp/log4j2-CVE-2021-45105 https://github.com/dileepdkumar/https-github.com-pravin-pp-log4j2-CVE-2021-45105-1 https://github.com/dileepdkumar/https-github.com-pravin-pp-log4j2-CVE-2021-45105 https://github.com/dileepdkumar/https-github.com-dileepdkumar-https-github.com-pravin-pp-log4j2-CVE-2021-45105-v htt • CWE-20: Improper Input Validation CWE-674: Uncontrolled Recursion •

An incomplete string comparison in the numpy.core component in NumPy before 1.22.0 allows attackers to trigger slightly incorrect copying by constructing specific string objects. NOTE: the vendor states that this reported code behavior is "completely harmless." Una comparación incompleta de cadenas en el componente numpy.core en NumPy en versiones anteriores a la 1.22.0, permite a los atacantes activar una copia ligeramente incorrecta mediante la construcción de objetos de cadena específicos. NOTA: el proveedor afirma que este comportamiento de código reportado es "completamente inofensivo". • https://github.com/numpy/numpy/issues/18993 https://www.oracle.com/security-alerts/cpujul2022.html • CWE-697: Incorrect Comparison •

lxml is a library for processing XML and HTML in the Python language. Prior to version 4.6.5, the HTML Cleaner in lxml.html lets certain crafted script content pass through, as well as script content in SVG files embedded using data URIs. Users that employ the HTML cleaner in a security relevant context should upgrade to lxml 4.6.5 to receive a patch. There are no known workarounds available. lxml es una biblioteca para procesar XML y HTML en el lenguaje Python. En versiones anteriores a 4.6.5, el limpiador de HTML en lxml.html dejaba pasar determinado contenido de scripts manipulados, así como contenido de scripts en archivos SVG insertados usando URIs de datos. • https://github.com/lxml/lxml/commit/12fa9669007180a7bb87d990c375cf91ca5b664a https://github.com/lxml/lxml/commit/a3eacbc0dcf1de1c822ec29fb7d090a4b1712a9c#diff-59130575b4fb2932c957db2922977d7d89afb0b2085357db1a14615a2fcad776 https://github.com/lxml/lxml/commit/f2330237440df7e8f39c3ad1b1aa8852be3b27c0 https://github.com/lxml/lxml/security/advisories/GHSA-55x5-fj6c-h6m8 https://lists.debian.org/debian-lts-announce/2021/12/msg00037.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TUIS2KE3HZ2AAQKXFLTJFZPP2IFHJTC7 https:/ • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. Netty prior to version 4.1.71.Final skips control chars when they are present at the beginning / end of the header name. It should instead fail fast as these are not allowed by the spec and could lead to HTTP request smuggling. Failing to do the validation might cause netty to "sanitize" header names before it forward these to another remote system when used as proxy. This remote system can't see the invalid usage anymore, and therefore does not do the validation itself. • https://github.com/netty/netty/commit/07aa6b5938a8b6ed7a6586e066400e2643897323 https://github.com/netty/netty/security/advisories/GHSA-wx5j-54mm-rqqq https://lists.debian.org/debian-lts-announce/2023/01/msg00008.html https://security.netapp.com/advisory/ntap-20220107-0003 https://www.debian.org/security/2023/dsa-5316 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2021-43797 https://bugzilla&# • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
