CVE-2023-41360 [CRITICAL] CWE-125 frr: ahead-of-stream read of ORF header
frr: ahead-of-stream read of ORF header
An issue was discovered in FRRouting FRR through 9.0. bgpd/bgp_packet.c can read the initial byte of the ORF header in an ahead-of-stream situation.
An out-of-bounds read flaw was found in FRRouting in bgpd/bgp_packet.c, resulting from a boundary condition. This flaw allows a remote attacker, through specially crafted input, to read the initial byte of the ORF header in an ahead-of-stream scenario. This attacker can gain information and potentially launch further attacks against the affected system.
Statement: In Red Hat Enterprise Linux 8, the vulnerable code is not included. It was added in FRR-8.4 in upstream. The highest version of FRR utilized in RHEL-8 is 7.5. Hence, versions of FRR shipped with RHEL-8 are not affected by this vulnerability.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
