![]() ![]() This happens because mod_proxy_cluster marks the JBoss EAP instance as an error worker when the TCP connection is closed from the backend after sending the AJP request without receiving an AJP response, and stops forwarding. When an AJP request is sent that exceeds the max-header-size attribute in ajp-listener, JBoss EAP is marked in an error state by mod_cluster in httpd, causing JBoss EAP to close the TCP connection without returning an AJP response. Reported by Jason Geffner.Ī flaw was found in Undertow. In Helix Core versions prior to 2023.2, an unauthenticated remote Denial of Service (DoS) via the buffer was identified. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. ![]() The set_ex_data function used by the library did not deallocate memory used by pre-existing data in memory each time after completing a TLS connection causing the program to consume more resources with each new connection.Ī possibility of unwanted server memory consumption was detected through the obsolete functionalities in the Rest API methods of the M-Files server before 6.0 which allows attackers to execute DoS attacks.Ī flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. The tokio-boring library in version 4.0.0 is affected by a memory leak issue that can lead to excessive resource consumption and potential DoS by resource exhaustion.
