Summary
Gitea parses Alpine package uploads before enforcing package-size quotas and does not bound the decompressed .PKGINFO data or its dependency and provides entry counts. An authenticated user with package-publish permission can upload a small, highly compressed archive that causes disproportionately large memory allocations during parsing and metadata generation. On memory-constrained deployments, this can terminate the process or otherwise disrupt availability.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of go-gitea/gitea published their own advisory on GitHub. Reviewed sources take precedence over it.
