high Nessus Plugin ID 352219

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2025:1762363302 advisory.

 - A reachable assertion was found in Frrouting frr-bgpd 8.3.0 in the peek_for_as4_capability function.
 Attackers can maliciously construct BGP open packets and send them to BGP peers running frr-bgpd, resulting in DoS. (CVE-2022-36440)

 - An issue found in Frrouting bgpd v.8.4.2 allows a remote attacker to cause a denial of service via the bgp_attr_psid_sub() function. (CVE-2023-31490)

 - 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. bgp_nlri_parse_flowspec in bgpd/bgp_flowspec.c processes malformed requests with no attributes, leading to a NULL pointer dereference. (CVE-2023-41909)

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 packages based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2025:1762363302.
