Debian Linux Security Advisory 5020-1 - Chen Zhaojun of Alibaba Cloud Security Team discovered a critical security vulnerability in Apache Log4j, a popular Logging Framework for Java. 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 version 2.15.0, this behavior has been disabled by default.

Debian Linux Security Advisory 5022-1 - It was found that the fix to address CVE-2021-44228 in Apache Log4j, a Logging Framework for Java, was incomplete in certain non-default configurations. This could allow attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in a denial of service (DOS) attack.

Debian Linux Security Advisory 5023-1 - It was discovered that modsecurity-apache, an Apache module to tighten the Web application security, does not properly handles excessively nested JSON objects, which could result in denial of service. The update introduces a new 'SecRequestBodyJsonDepthLimit' option to limit the maximum request body JSON parsing depth which ModSecurity will accept (defaults to 10000).

Debian Linux Security Advisory 5024-1 - It was found that Apache Log4j2, a Logging Framework for Java, did not protect from uncontrolled recursion from self-referential lookups. When the logging configuration uses a non-default Pattern Layout with a Context Lookup (for example, $${ctx:loginId}), attackers with control over Thread Context Map (MDC) input data can craft malicious input data that contains a recursive lookup, resulting in a denial of service.
