18 Dez 2021 Jahr - CVE-2021-45105 CVSSv3.1: 7.5 HIGH Log4j 2.0-alpha1<= 2.16.0 DoS PATCH to v2.17

Beschreibung:

Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3) 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 and 2.12.3.
