** UNSUPPORTED WHEN ASSIGNED **
When using the Chainsaw or SocketAppender components with Log4j 1.x on JRE less than 1.7, an attacker that manages to cause a logging entry involving a specially-crafted (ie, deeply nested)
hashmap or hashtable (depending on which logging component is in use) to be processed could exhaust the available memory in the virtual machine and achieve Denial of Service when the object is deserialized.
This issue affects Apache Log4j before 2. Affected users are recommended to update to Log4j 2.x.
NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
A flaw was found in Chainsaw and SocketAppender components with Log4j 1.x on JRE, less than 1.7. This issue may allow an attacker to use a logging entry with a specially-crafted hashmap or hashtable, depending on which logging component is in use, to process and exhaust the available memory in the virtual machine, resulting in a Denial of Service when the object is deserialized. This issue affects Apache Log4j before version 2.
Отчет
Red Hat Enterprise Linux 8 and 9 security impacts have been reduced to Low as they do not enable the vulnerable JDK by default.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
