In FRRouting (FRR) before 10.3 from 6.0 onward, all routes are re-validated if the total size of an update received via RTR exceeds the internal socket's buffer size, default 4K on most OSes. An attacker can use this to trigger re-parsing of the RIB for FRR routers using RTR by causing more than this number of updates during an update interval (usually 30 minutes). Additionally, this effect regularly occurs organically. Furthermore, an attacker can use this to trigger route validation continuously. Given that routers with large full tables may need more than 30 minutes to fully re-validate the table, continuous issuance/withdrawal of large numbers of ROA may be used to impact the route handling performance of all FRR instances using RPKI globally. Additionally, the re-validation will cause heightened BMP traffic to ingestors. Fixed Versions: 10.0.3, 10.1.2, 10.2.1, >= 10.3.

Iggy Frankovic discovered that FRR incorrectly handled certain BGP
messages. A remote attacker could possibly use this issue to cause FRR to
crash, resulting in a denial of service. This issue only affected Ubuntu
20.04 LTS. (CVE-2024-44070)
It was discovered that FRR re-validated all routes in certain instances
when the internal socket's buffer size overflowed. A remote attacker could
possibly use this issue to impact the performance of FRR, resulting in a
denial of service. (CVE-2024-55553)

CVE-2024-55553 GHSA-hrrq-wpmq-47mf: In FRRouting (FRR) before 10
In FRRouting (FRR) before 10.3, it is possible for an attacker to trigger repeated RIB revalidation by sending approximately 500 RPKI updates, potentially leading to prolonged revalidation times and a Denial of Service (DoS) scenario.

CVE-2024-55553 [HIGH] FRR vulnerabilities
Title: FRR vulnerabilities
Summary: FRR could be made to crash or exhibit degraded performance if it received
specially crafted network traffic.
Iggy Frankovic discovered that FRR incorrectly handled certain BGP
messages. A remote attacker could possibly use this issue to cause FRR to
crash, resulting in a denial of service. This issue only affected Ubuntu
20.04 LTS. (CVE-2024-44070)
It was discovered that FRR re-validated all routes in certain instances
when the internal socket's buffer size overflowed. A remote attacker could
possibly use this issue to impact the performance of FRR, resulting in a
denial of service. (CVE-2024-55553)
Instructions: In general, a standard system update will make all the necessary changes.
