Integer overflow in the authenticatepost function in CGit before 0.12 allows remote attackers to have unspecified impact via a large value in the Content-Length HTTP header, which triggers a buffer overflow.

Directory traversal vulnerability in the cgitparsereadme function in ui-summary.c in cgit before 0.9.2, when a readme file is set to a filesystem path, allows remote attackers to read arbitrary files via a .. (dot dot) in the url parameter.

CRLF injection vulnerability in the ui-blob handler in CGit before 0.12 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks or cross-site scripting (XSS) attacks via CRLF sequences in the mimetype parameter, as demonstrated by a request to blob/cgit.c.

CRLF injection vulnerability in the cgitprinthttpheaders function in ui-shared.c in CGit before 0.12 allows remote attackers with permission to write to a repository to inject arbitrary HTTP headers and conduct HTTP response splitting attacks or cross-site scripting (XSS) attacks via newline characters in a filename.
