description
IBM MQ Operator and MQ Advanced container images are affected by a stack buffer overflow in TLS certificate handling. A remote attacker may execute code if the service processes a certificate with a malformed distinguished name during channel establishment.
mitigation
Upgrade MQ Operator to version 3.4.0. For MQ Advanced container images, restrict TLS channel establishment to trusted peers and limit network access until a vendor-fixed image version is identified.
fixed in 3.4.0
