Descriptions

Off-by-one error in the convert_query_hexchar function in html.c in cgit.cgi in cgit before 0.8.3.5 allows remote attackers to cause a denial of service (infinite loop) via a string composed of a % (percent) character followed by invalid hex characters, as demonstrated by a %gg sequence.
