## How to fix

- Fixed in EPICS Base 7.0.11

## Technical details

Insufficient validation of element or length values in network messages causes an out-of-bounds read when the application accesses a buffer. This is a network-accessible vulnerability requiring no authentication or user interaction; an attacker can send a specially crafted message to trigger the condition, leading to denial of service or information disclosure of adjacent memory contents.

## Affected products

- EPICS Community EPICS Base 7.0.10 and prior
