apko affected by potential unbounded resource consumption in expandapk.ExpandApk on attacker-controlled .apk streams

apko allows users to build and publish OCI container images built from apk packages. From version 0.14.8 to before 1.1.1, an attacker who controls or compromises an APK repository used by apko could cause resource exhaustion on the build host. The ExpandApk function in pkg/apk/expandapk/expandapk.go expands .apk streams without enforcing decompression limits, allowing a malicious repository to serve a small, highly-compressed .apk that inflates into a large tar stream, consuming excessive disk space and CPU time, causing build failures or denial of service. This issue has been patched in version 1.1.1.

未加控制的资源消耗(资源穷尽)

apko 资源管理错误漏洞

apko是apko开源的一个基于 apk 的 OCI 镜像构建器。 apko 0.14.8版本至1.1.1之前版本存在资源管理错误漏洞，该漏洞源于ExpandApk函数未强制执行解压缩限制，可能导致资源耗尽、构建失败或拒绝服务。
