Description

This security bulletin contains information about 1 vulnerability.


1) Improper handling of exceptional conditions (CVE-ID: CVE-2024-47491)

CWE-ID: CWE-755 - Improper Handling of Exceptional Conditions

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to improper handling of exceptional conditions error in the Routing Protocol Daemon (rpd). A remote non-authenticated attacker can cause Denial of Service (DoS).

When a BGP UPDATE with malformed path attribute is received over an established BGP session, rpd crashes and restarts.

Continuous receipt of a BGP UPDATE with a specifically malformed path attribute will create a sustained Denial of Service (DoS) condition for impacted devices.
