Vulnerability details
The vulnerability allows a remote user to cause a denial of service.
The vulnerability exists due to uncontrolled resource consumption in the Alpine package upload handler when parsing an uploaded .apk file before package-size quota checks. A remote user can upload a small, highly compressible .apk with a .PKGINFO file containing a very large number of provides= lines to cause a denial of service.
The parsed metadata may remain allocated after serialization into package metadata and repository index rebuilding, increasing memory pressure. On memory-constrained deployments, the process may be terminated by the out-of-memory killer.
