CVE-2020-17529— Apache NuttX (incubating) Out of Bound Write from invalid fragmentation offset value specified in the IP header

Quick assessment

Affected
Apache Software Foundation Apache NuttX (incubating)
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache NuttX是美国阿帕奇软件（Apache Software）基金会的一套实时嵌入式操作系统。TCP（Transmission Control Protocol,传输控制协议）是一种面向连接的、可靠的、基于字节流的传输层通信协议，由IETF的RFC 793定义。 Apache NuttX 存在安全漏洞，该漏洞源于9.1.0和10.0.0允许攻击者可利用该漏洞通过提供IP报头中指定的无效碎片偏移值来破坏内存。这只会影响配置实验和配置网TCP重新组装构建标志都启用的构建。
