GIMP 中存在一个漏洞。XCF 加载器在通过选择属性销毁已链接的通道后，可能会在已链接通道列表中留下悬空指针。打开一个特制的 XCF 文件可能导致主 GIMP 进程出现释放后使用（use-after-free）漏洞，从而引发程序崩溃，甚至可能导致任意代码执行。

Vulnerability Description
A flaw was found in GIMP. The XCF loader can leave a dangling pointer in the linked-channels list when a linked channel is later destroyed via a selection property.
