Chainguard: multiple keycloak-26.8 packages: security update to 26.8.1-r4

medium Tenable Cloud Security Plugin ID 478130

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - MariaDB Connector/J is used to connect applications developed in Java to MariaDB and MySQL databases. From
 3.0.0 until 3.3.7, 3.4.5, and 3.5.11, when CLIENT_SESSION_TRACK was negotiated, the OkPacket.parse() and
 OkPacket.parseWithInfo() paths allocated byte arrays using server-declared lengths for the OK packet info
 field and session-state variable names and values before confirming that the bytes remained in the packet.
 A malicious or compromised server, or a machine-in-the-middle attacker, could send a small OK packet
 declaring a much larger length and repeatedly force attacker-controlled heap allocations before the
 subsequent copy failed. This could create garbage-collection pressure or an OutOfMemoryError in the client
 application. This issue is fixed in versions 3.3.7, 3.4.5, and 3.5.11. (CVE-2026-119276)

Solution

Update the keycloak-26.8 library and its related packages to version 26.8.1-r4 or later.
