# CVE-2020-11061: Heap-based Buffer Overflow in Bareos Director

- Severity: CVSS 6.0 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:L
- Known exploited (CISA KEV): no
- Published: 2020-07-10 · Updated: 2024-08-04

## Affected

- Bareos GmbH & Co. KG Bareos Director: through 16.2.10; through 17.2.9; through 18.2.8; through 19.2.7

## Description

In Bareos Director less than or equal to 16.2.10, 17.2.9, 18.2.8, and 19.2.7, a heap overflow allows a malicious client to corrupt the director's memory via oversized digest strings sent during initialization of a verify job. Disabling verify jobs mitigates the problem. This issue is also patched in Bareos versions 19.2.8, 18.2.9 and 17.2.10.
