CVE-2023-41361 [CRITICAL] CWE-120 frr: does not check for an overly large length of the rcv software version
frr: does not check for an overly large length of the rcv software version
An issue was discovered in FRRouting FRR 9.0. bgpd/bgp_open.c does not check for an overly large length of the rcv software version.
A vulnerability was found in FRRouting stemming from a boundary error in bgpd/bgp_open.c. The issue arises because it fails to check for an excessively large length of the received software version (rcv). This flaw allows a remote attacker to overflow a buffer by sending specially crafted data to the application, leading to a denial of service condition.
Statement: In Red Hat Enterprise Linux 8 and 9, the vulnerable code is not included. It was added much later during the development of the 9.x version of FRR in upstream. The highest version of FRR utilized in RHEL is 8.5. Consequen

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.
