imgproxy：ICO图片尺寸计算可能溢出

11月8日公开的漏洞记录CVE-2026-123614涉及imgproxy。问题出在图像代理读取ICO图标时。一项尺寸数据先参与整数运算，再用于申请内存。如果计算结果回绕，实际留出的缓冲区就可能小于后续写入的数据量。接收外部提交图片的服务可能因此崩溃，公告还列出在进程中执行代码的风险。版本清单标出的受影响范围包括4.0.0起至4.0.16之前。记录另将4.0.16列为不受影响的版本。

这条记录给出的CVSS 3.1基础评分为9.8分，分级为严重。按照评分列出的条件，利用者可通过网络接触相关功能，不以事先取得系统权限为必要条件，并且无需另一名用户进行额外交互。数据保密性、内容完整性和服务可用性三项的影响等级分别为高、高、高。评分把利用复杂度列为较低，所反映的是触发这一缺陷需要满足的技术条件。
