2) Out-of-bounds read

EUVDB-ID: #VU82898

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-38407

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition during labeled unicast parsing in bgpd/bgp_label.c. A remote attacker can send specially crafted input to the application, trigger an out-of-bounds read error and crash the daemon.

3) Input validation error

EUVDB-ID: #VU82899

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-47234

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input when processing a crafted BGP UPDATE message with a MP_UNREACH_NLRI attribute and additional NLRI data (that lacks mandatory path attributes). A remote attacker can send specially crafted messages to the daemon and perform a denial of service (DoS) attack.

Mitigation

Update the affected package frr to the latest version.
