CVE-2023-41359 [CRITICAL] CWE-125 frr: out of bounds read in bgp_attr_aigp_valid
frr: out of bounds read in bgp_attr_aigp_valid
An issue was discovered in FRRouting FRR through 9.0. There is an out-of-bounds read in bgp_attr_aigp_valid in bgpd/bgp_attr.c because there is no check for the availability of two bytes during AIGP validation.
A flaw was found in FRRouting that involves a heap-based buffer overflow in the bgp_attr_aigp_valid() function within bgpd/bgp_attr.c. This flaw allows a remote attacker to send specially crafted data to the application, initiating an out-of-bounds read error and executing a denial of service (DoS) attack.
Statement: In Red Hat Enterprise Linux 8, the vulnerable code is not included. It was added in FRR-8.5 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 b

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
