Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2024-0130 advisory.

- bgpd/bgp_label.c in FRRouting (FRR) before 8.5 attempts to read beyond the end of the stream during labeled unicast parsing. (CVE-2023-38407)

- An issue was discovered in FRRouting FRR through 9.0.1. A crash can occur when processing a crafted BGP UPDATE message with a MP_UNREACH_NLRI attribute and additional NLRI data (that lacks mandatory path attributes). (CVE-2023-47234)

- An issue was discovered in FRRouting FRR through 9.0.1. A crash can occur when a malformed BGP UPDATE message with an EOR is processed, because the presence of EOR does not lead to a treat-as-withdraw outcome. (CVE-2023-47235)

- bgpd/bgp_flowspec.c in FRRouting (FRR) before 8.4.3 mishandles an nlri length of zero, aka a flowspec overflow. (CVE-2023-38406)

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

Solution

Update the affected frr and / or frr-selinux packages.
