In EPICS Base release 7.0.10 and prior, an integer overflow in network request processing can cause memory to be allocated with an incorrect size. Subsequent handling of attacker supplied data may result in memory corruption, denial of service, or potential remote code execution.
The EPICS Community has made available updates to the epics-base GitHub repositories. Affected users should update to the 7.0.11 release. For more information, users should contact the EPICS Controls team https://epics-controls.org/support/.
