Vulnerability Title
Cisco IOS XR Software Cisco Discovery Protocol Buffer Overflow Vulnerability
Vulnerability Description
A vulnerability in the Cisco Discovery Protocol implementation for Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause the Cisco Discovery Protocol process to reload on an affected device. This vulnerability is due to a heap buffer overflow in certain Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device. A successful exploit could allow the attacker to cause a heap overflow, which could cause the Cisco Discovery Protocol process to reload on the device. The bytes that can be written in the buffer overflow are restricted, which limits remote code execution.Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent). Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.This advisory is part of the September 2022 release of the Cisco IOS XR Software Security Advisory Bundled Publication.

Vulnerability Title
Cisco IOS XR 安全漏洞
Vulnerability Description
Cisco IOS XR是美国思科（Cisco）公司的一套为其网络设备开发的操作系统。 Cisco IOS XR Software Cisco Discovery Protocol implementation存在安全漏洞，该漏洞源于某些消息中的堆缓冲区溢出造成的，攻击者可以通过向受影响的设备发送恶意数据包来利用此漏洞，可能允许未经身份验证的相邻攻击者导致进程在受影响的设备上重新加载，成功利用可能允许攻击者导致堆溢出，缓冲区溢出中可以写入的字节受到限制，从而限制远程代码执行。
