Description

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]
