critical Nessus Plugin ID 185781

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6482-1 advisory.

 - An out-of-bounds read in the BGP daemon of FRRouting FRR before 8.4 may lead to a segmentation fault and denial of service. This occurs in bgp_capability_msg_parse in bgpd/bgp_packet.c. (CVE-2022-37032)

 - An issue was discovered in FRRouting FRR through 9.0.1. A crash can occur for a crafted BGP UPDATE message without mandatory attributes, e.g., one with only an unknown transit attribute. (CVE-2023-46753)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution
