CVE-2021-43818 – HTML Cleaner allows crafted and SVG embedded scripts to pass through
https://notcve.org/view.php?id=CVE-2021-43818
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') •

A stack-based buffer overflow in handle_request function in DHT.c in toxcore 0.1.9 through 0.1.11 and 0.2.0 through 0.2.12 (caused by an improper length calculation during the handling of received network packets) allows remote attackers to crash the process or potentially execute arbitrary code via a network packet.

CVE-2021-44228 – Apache Log4j2 Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-44228
Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects. • https://github.com/fullhunt/log4j-scan https://github.com/Puliczek/CVE-2021-44228-PoC-log4j-bypass-words https://github.com/cyberstruggle/L4sh https://github.com/woodpecker-appstore/log4j-payload-generator https://github.com/tangxiaofeng7/apache-log4j-poc https://www.exploit-db.com/exploits/51183 https://www.exploit-db.com/exploits/50592 https://www.exploit-db.com/exploits/50590 https://github.com/logpresso/CVE-2021-44228-Scanner https://github.com/jas502n/Log4j2-CVE-2021-44228 h • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption CWE-502: Deserialization of Untrusted Data CWE-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection') •
