Security update for log4j

Notes

Title of the patch
Security update for log4j
Description of the patch
This update for log4j fixes the following issue: CVE-2021-44228: The previously published fix by upstream turned out to be incomplete. Therefore, upstream has recommended disabling JNDI support in log4j by default to be completely sure that this vulnerability cannot be exploited. This update implements that recommendation and disables JNDI support by default. [bsc#1193611, CVE-2021-44228] CVE-2021-45046: A Thread Context Message Pattern and Context Lookup Pattern vulnerable to a denial of service attack is also fixed by disabling JNDI support by default (bsc#1193743)

This could allows 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 an information leak and remote code execution in some environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix this issue by removing support for message lookup patterns and disabling JNDI functionality by default.",
