## How to fix

- Fixed in 7.0.11

## Technical details

Insufficient validation of element or length values in network protocol messages enables out-of-bounds memory reads in EPICS Base 7.0.10 and prior. The vulnerability is triggered by network packets containing malformed length parameters, allowing attackers with network access to read adjacent memory without authentication. Exploitation results in denial of service and information disclosure of adjacent memory regions; a fix is available in version 7.0.11.
