https://notcve.org/view.php?id=CVE-2021-4203
A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a user privileges may crash the system or leak internal kernel information.

CVE-2022-0391 – python: urllib.parse does not sanitize URLs containing ASCII newline and tabs
https://notcve.org/view.php?id=CVE-2022-0391
A flaw was found in Python, specifically within the urllib.parse module. This module helps break Uniform Resource Locator (URL) strings into components. The issue involves how the urlparse method does not sanitize input and allows characters like '\r' and '\n' in the URL path. This flaw allows an attacker to input a crafted URL, leading to injection attacks. This flaw affects Python versions prior to 3.10.0b1, 3.9.5, 3.8.11, 3.7.11 and 3.6.14. • https://bugs.python.org/issue43882 https://lists.debian.org/debian-lts-announce/2023/09/msg00022.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CSD2YBXP3ZF44E44QMIIAR5VTO35KTRB https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UDBDBAU6HUPZHISBOARTXZ5GKHF2VH5U https://security.gentoo.org/glsa/202305-02 https://security.netapp.com/advisory/ntap-20220225-0009 https://www.oracle.com/security-alerts/cpuapr2022.html https://access. • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
CVE-2022-23437 – Infinite loop within Apache XercesJ xml parser
https://notcve.org/view.php?id=CVE-2022-23437
There's a vulnerability within the Apache Xerces Java (XercesJ) XML parser when handling specially crafted XML document payloads. This causes, the XercesJ XML parser to wait in an infinite loop, which may sometimes consume system resources for prolonged duration. This vulnerability is present within XercesJ version 2.12.1 and the previous versions. Se presenta una vulnerabilidad en el analizador XML de Apache Xerces Java (XercesJ) cuando maneja cargas útiles de documentos XML especialmente diseñados. Esto causa que el analizador XML de XercesJ espere en un bucle infinito, lo que a veces puede consumir recursos del sistema durante un tiempo prolongado. • http://www.openwall.com/lists/oss-security/2022/01/24/3 https://lists.apache.org/thread/6pjwm10bb69kq955fzr1n0nflnjd27dl https://security.netapp.com/advisory/ntap-20221028-0005 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-23437 https://bugzilla.redhat.com/show_bug.cgi?id=2047200 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2021-44790 – Possible buffer overflow when parsing multipart content in mod_lua of Apache HTTP Server 2.4.51 and earlier
https://notcve.org/view.php?id=CVE-2021-44790
A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier. Un cuerpo de petición cuidadosamente diseñado puede causar un desbordamiento de búfer en el analizador multiparte mod_lua (r:parsebody() llamado desde scripts Lua). El equipo de Apache httpd no presenta constancia de que se presente una explotación para esta vulnerabilidad, aunque podría ser posible diseñar uno. • https://www.exploit-db.com/exploits/51193 https://github.com/nuPacaChi/-CVE-2021-44790 http://httpd.apache.org/security/vulnerabilities_24.html http://packetstormsecurity.com/files/171631/Apache-2.4.x-Buffer-Overflow.html http://seclists.org/fulldisclosure/2022/May/33 http://seclists.org/fulldisclosure/2022/May/35 http://seclists.org/fulldisclosure/2022/May/38 http://www.openwall.com/lists/oss-security/2021/12/20/4 https://lists.fedoraproject.org/archives/list/package-announce • CWE-787: Out-of-bounds Write •
CVE-2021-45105 – Apache Log4j2 does not always protect from infinite recursion in lookup evaluation
https://notcve.org/view.php?id=CVE-2021-45105
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 •
