Beschreibung:	Summary: The remote host is missing an update for the 'log4j' package(s) announced via the MGASA-2021-0566 advisory. Vulnerability Insight: It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-default configurations. 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 a denial of service (DOS) attack. Log4j 2.15.0 makes a best-effort attempt to restrict JNDI LDAP lookups to localhost by default. Log4j 2.16.0 fixes this issue by removing support for message lookup patterns and disabling JNDI functionality by default (CVE-2021-45046). Affected Software/OS: 'log4j' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 5.1 CVSS Vector: AV:N/AC:H/Au:N/C:P/I:P/A:P
