Vulnerability Title
ImageMagick's policy bypass through path traversal allows reading restricted content despite secured policy
Vulnerability Description
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, ImageMagick’s path security policy is enforced on the raw filename string before the filesystem resolves it. As a result, a policy rule such as /etc/* can be bypassed by a path traversal. The OS resolves the traversal and opens the sensitive file, but the policy matcher only sees the unnormalized path and therefore allows the read. This enables local file disclosure (LFI) even when policy-secure.xml is applied. Actions to prevent reading from files have been taken in versions .7.1.2-15 and 6.9.13-40 But it make sure writing is also not possible the following should be added to one's policy. This will also be included in ImageMagick's more secure policies by default.

对路径名的限制不恰当(路径遍历)
Vulnerability Title
ImageMagick 路径遍历漏洞
Vulnerability Description
ImageMagick是ImageMagick开源的一套开源的图像处理软件。可读取、转换或写入多种格式的图片。 ImageMagick 7.1.2-15之前版本和6.9.13-40之前版本存在路径遍历漏洞，该漏洞源于路径安全策略在文件系统解析原始文件名字符串之前强制执行，可能导致路径遍历绕过策略，造成本地文件泄露。
