Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Out-of-bounds write

EUVDB-ID: #VU69943

Risk: Low

CVSSv3.1: 5.6 [CVSS:3.1/AV:P/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-2347

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows an attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error in the U-Boot DFU implementation when processing download setup packets. An attacker with physical access to device can send a USB DFU download setup packet with a `wLength` greater than 4096 bytes, trigger a heap-based buffer overflow and execute arbitrary code on the system.

Mitigation

Update the affected package u-boot to the latest version.
