在 1.6.20 之前以及 1.7.x 系列中 1.7.5 之前的 Roundcube Webmail 版本中，在生成缩略图时存在绕过 ImageMagick 资源限制的问题。当 回退到使用 GD 库时，可用内存检查仅在 Windows 平台上生效；因此在其他平台上，攻击者可构造尺寸巨大的恶意图像，由 GD 库在无资源限制的情况下处理，从而导致服务器内存耗尽。上游已在提交"Fix ImageMagick resource limits bypass by GD fallback during thumbnail g

Vulnerability Description
Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 allows the ImageMagick resource limits to be bypassed during thumbnail generation. When rcube_image falls back to GD, the available-memory check was applied only on Windows, so on other platforms a crafted image with large dimensions was processed by GD without any resource limit and could exhaust server memory. Upstream fixed this in the commit “Fix ImageMagick resource limits bypass by GD fallback during thumbnail generation”, which applies the memory check on all platforms.
