Title

Quagga栈缓冲区溢出漏洞

Description

Quagga是一款路由软件套件。该套件可在多种平台上实现OSPFv2、OSPFv3、RIP v1/v2等协议，并提供路由重分布、路由映射等功能。 Quagga的bgp_mplsvpn.c文件的VPNv4 NLRI解析器中的‘memcpy函数未能正确检查Labeled-VPN SAFI数据的upper-bound长度，允许远程攻击者利用该漏洞提交特殊请求执行任意代码。

CVE-2016-2342 (GCVE-0-2016-2342)

Vulnerability from cvelistv5 – Published: 2016-03-17 14:00 – Updated: 2024-08-05 23:24

Summary

The bgp_nlri_parse_vpnv4 function in bgp_mplsvpn.c in the VPNv4 NLRI parser in bgpd in Quagga before 1.0.20160309, when a certain VPNv4 configuration is used, relies on a Labeled-VPN SAFI routes-data length field during a data copy, which allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow) via a crafted packet.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
