中危 cloudflare octorpki 跨界内存写
CVE编号
CVE-2021-3761利用情况
暂无补丁情况
官方补丁披露时间
2021-09-09漏洞描述
Any CA issuer in the RPKI can trick OctoRPKI prior to 1.3.0 into emitting an invalid VRP "MaxLength" value, causing RTR sessions to terminate. An attacker can use this to disable RPKI Origin Validation in a victim network (for example AS 13335 - Cloudflare) prior to launching a BGP hijack which during normal operations would be rejected as "RPKI invalid". Additionally, in certain deployments RTR session flapping in and of itself also could cause BGP routing churn, causing availability issues.解决建议
建议您更新当前系统或软件至最新版，完成漏洞的修复。
