An integer overflow issue was found in Uriparser in the ComposeQueryEngine() function in UriQuery.c. This function computes the space needed for composing a query string. However, it encounters an integer overflow issue when handling large key or value lengths, potentially leading to incorrect memory allocations or operations due to malformed size calculations. This flaw allows attackers to crash the application, resulting in a denial of service.
