2) Out-of-bounds read

EUVDB-ID: #VU67277

Risk: Medium

CVSSv3.1: 4.3 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:L/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-37032

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition when processing BGP messages. A remote attacker can send specially crafted BGP messages to the system, trigger an out-of-bounds read error and read contents of memory on the system or crash the BGP daemon.

Mitigation

Update the affected package frr to the latest version.
