- ------------------------------------------------------------------------- Debian LTS Advisory DLA-4029-1 [email protected] https://www.debian.org/lts/security/ Arturo Borrero Gonzalez January 23, 2025 https://wiki.debian.org/LTS - ------------------------------------------------------------------------- Package : frr Version : 7.5.1-1.1+deb11u4 CVE ID : CVE-2024-55553 In FRR, the internet routing protocol suite software, 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. For Debian 11 bullseye, this problem has been fixed in version 7.5.1-1.1+deb11u4. We recommend that you upgrade your frr packages.
