CVE-2026-58227— Erlang OTP 资源管理错误漏洞

TLS/DTLS denial of service via unbounded recursion on cross-signed peer certificate chain

The Erlang/OTP ssl application does not detect cycles when reconstructing an incomplete peer certificate chain during a TLS or DTLS handshake. In ssl_certificate:handle_incomplete_chain/5, the received chain is passed to ssl_certificate:build_certificate_chain/5, which walks issuer relationships via ssl_certificate:do_certificate_chain/7 with no cycle detection and no depth limit. When the peer supplies two mutually cross-signed certificates in unordered form (A issues B, B issues A), the issuer lookup alternates between the two certificates and the pair of functions recurses indefinitely, growing the call stack and chain accumulator without bound. An unauthenticated remote attacker can send a crafted certificate chain in a TLS or DTLS Certificate handshake message to exhaust available memory and crash the BEAM node. Only a TCP connection and a partial handshake are required; no authentication or completed handshake is needed, and both TLS/DTLS servers and clients are affected when processing peer certificate messages. This issue affects OTP from OTP 23.2 before OTP 29.0.4, OTP 28.5.0.4 and OTP 27.3.4.15, corresponding to ssl from 10.2 before 11.7.4, 11.6.0.4 and 11.2.12.11.

未经控制的递归

Erlang OTP 资源管理错误漏洞

Erlang OTP是瑞典Erlang社区的一套构建分布式系统的中间件平台。 Erlang OTP 23.2版本至29.0.4之前版本、28.5.0.4版本和27.3.4.15版本存在资源管理错误漏洞，该漏洞源于在TLS或DTLS握手重建不完整的对等证书链时未检测循环，导致未经身份验证的远程攻击者可通过发送特制证书链，耗尽内存并导致BEAM节点崩溃。
