| 不受影响 | 不受影响-漏洞代码不在执行路径 | 易受影响的代码在执行过程中不可访问,包括产品的非预期状态。产品不使用也不执行的组件。 |
| 不受影响 | 不受影响-漏洞代码不存在 | 产品不受影响,因为漏洞背后的代码在产品中不存在。与component_not_present不同的是,有问题的组件存在,但由于某种原因(例如安全的编译器选项)使漏洞的特定代码不存在于组件中。 |

影响性分析说明:Squid is a caching proxy for the Web. From 3.3.0.1 to before 7.6, due to an improper enforcement of behavioral workflow bug, Squid is vulnerable to a Request Smuggling attack against HTTP/1.1 Transfer-Encoding. HTTP header parsing (src/HttpHeader.cc) accepted the bare Transfer-Encoding: identity form, which the HTTP specification prohibits because any transfer coding must be wrapped within chunked encoding. This problem allows a trusted client to perform an HTTP Request Smuggling attack when HTTP/1.1 is used, bypassing security mechanisms that may be in place between attacker and Squid. When there is an HTTP cache operating prior to the affected Squid, this Request Smuggling attack also allows the attacker to poison that web cache and store arbitrary malicious content at any URL for delivery to other clients' future requests. This issue is fixed in version 7.6.

【任务 #83 · openEuler-22.03-LTS-SP4】CVE-2026-61642
1. 受影响性结论:受影响
squid 4.9 的 HttpHeader::parse()(src/HttpHeader.cc:323-490)第 466-467 行存在对 bare Transfer-Encoding: identity 的接受分支(rawTe == "identity" 时直接 delById(TRANSFER_ENCODING)),该漏洞代码存在于本版本源码且补丁未应用,需要修复。

3. 补丁适配情况(backport-CVE-2026-61642.patch:已适配,置信度 high)
- 冲突原因:原补丁基于上游 v7 版
HttpHeader::parse()(@@ -509,8),与 squid-4.9 存在版本差异:4.9 使用rawTe == "identity"(大小写敏感的 String::operator==)而非上游的rawTe.caseCmp("identity") == 0;前置上下文if (rawTe == "chunked")写法与上游 caseCmp 版本不匹配;行号偏移(上游 509 → 4.9 的 466);hunk 头 parse 函数签名不同(v7 多一个 ContentLengthInterpreter 相关参数),故git apply --check失败,需适配。 - 适配内容:按补丁意图整体删除 4.9 中 identity 接受分支的两行(
} else if (rawTe == "identity") { // deprecated. no coding与delById(Http::HdrType::TRANSFER_ENCODING);),使 bareTransfer-Encoding: identity落入 else 的 unsupported 分支(warning +teUnsupported_ = true)。适配补丁的-行与 baseline 实际代码逐字节一致,与原补丁的 caseCmp 差异属版本间已存在的代码差异;baseline 第 471 行teUnsupported_ = true;不在补丁改动范围内,保留不动。核心修复逻辑保真。 - 落地验证:适配补丁已应用到源码目录(git commit 06253d2,
git diff --stat确认src/HttpHeader.cc | 2 --),正向apply --check与反向--check --reverse均验证通过。 - 前置补丁:无。

This problem allows a trusted client to perform an HTTP Request Smuggling attack when HTTP/1.1 is used, bypassing security mechanisms that may be in place between attacker and Squid.
