原因说明填写请参考下方表格(注意：版本是否受影响和版本的原因说明必须对应，例如master版本分支受影响，那原因说明只能是受影响对应的原因之一!)：
分支状态 |
原因说明 | 使用场景 |
|---|---|---|
| 受影响 | 正常修复 | 受影响且需要修复（包含升级版本修复）的漏洞； 受影响且已经修复的漏洞（历史修复PR也需要关联issue）； 若因特殊原因无法修复，应修改原因说明为【不修复-特殊原因】，并在安委会备案相关情况。 |
| 受影响 | 暂不修复-漏洞仍在分析中 | 已关注到相关漏洞，正在处理，未明确漏洞影响和修复方案。 |
| 受影响 | 暂不修复-暂无解决方案或补丁 | 当前没有可用的修复或补救措施。【影响性分析】中应包含有关为什么没有修复或补救措施的详细说明、上游相关PR等。 |
| 受影响 | 不修复-超出修复范围 | 没有漏洞的修复计划。当版本停维、软件包宣布生命周期终止或弃用使用。 |
| 受影响 | 不修复-特殊原因导致不再修复 | 如存在其他特殊情况不修复相关漏洞，或评估后无法升级修复，应在openEuler社区安全委员会例会进行说明备案。 【影响性分析】中应包含不发布修复的详细说明、特殊情况还应有安委会会议纪要。 |
| 不受影响 | 不受影响-组件不存在 | 软件不受影响，因为易受攻击的组件不在产品中。 |
| 不受影响 | 不受影响-已有内置的内联控制或缓解措施 | 内置的内联控制或缓解措施可防止攻击者利用漏洞 |
| 不受影响 | 不受影响-漏洞代码不能被攻击者触发 | 易受攻击的组件存在，并且该组件包含易受攻击的代码。但是，易受攻击的代码的使用方式使得攻击者无法进行任何预期的攻击。 |
| 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：A vulnerability exists in NGINX Plus and NGINX Open Source when a map directive uses regex matching and the root directive or access log format references the map s regex capture variables before referencing the map output variable. Alternatively, the same result could be achieved by using a non-cacheable variable in a string expression under certain conditions. An unauthenticated attacker along with conditions beyond their control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR.Impact: This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system or to possibly trigger a code execution. There is no control plane exposure; this is a data plane issue only.

漏洞简述：
A vulnerability exists in NGINX Plus and NGINX Open Source when a map directive uses regex matching and the root directive or access log format references the map s regex capture variables before referencing the map output variable. Alternatively, the same result could be achieved by using a non-cacheable variable in a string expression under certain conditions. An unauthenticated attacker along with conditions beyond their control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR.Impact: This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system or to possibly trigger a code execution. There is no control plane exposure; this is a data plane issue only.Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
