Gogs: Denial of Service in repository/wiki file listing web pages

Gogs is an open source self-hosted Git service. Prior to 0.14.3, a malicious user with rights to create a new file on a repository or wiki page can trigger a denial of service condition in which the pages containing the listing of files will return HTTP error 500 and render the web interface unusable for the repository or wiki. The issue is present in file internal/route/repo/wiki.go and internal/route/repo/view.go where the pages try to recover commit information. If errors are returned while recovering commit information, the page will return a 500 error and stop rendering, resulting in a denial of service. This vulnerability is fixed in 0.14.3.
