Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the ExpandApk function. An attacker can cause excessive resource consumption by providing a specially crafted, highly-compressed .apk stream that decompresses into a large tar archive, leading to disk space and CPU exhaustion on the build host.
