Uriparser Project ≫ Uriparser

In uriparser before 1.0.2, the function family EqualsUri can misclassify two unequal URIs as equal.

In uriparser before 1.0.2, there is pointer difference truncation to int in various places.

uriparser before 1.0.1 has numeric truncation in text range comparison, if an application accepts URIs with a length in gigabytes.

uriparser through 0.9.9 allows unbounded recursion and stack consumption, as demonstrated by ParseMustBeSegmentNzNc with large input containing many commas.

An issue was discovered in uriparser through 0.9.7. ComposeQueryEngine in UriQuery.c has an integer overflow via long keys or values, with a resultant buffer overflow.

An issue was discovered in uriparser through 0.9.7. ComposeQueryMallocExMm in UriQuery.c has an integer overflow via a long string.

An issue was discovered in uriparser before 0.9.6. It performs invalid free operations in uriFreeUriMembers and uriMakeOwner.

An issue was discovered in uriparser before 0.9.6. It performs invalid free operations in uriNormalizeSyntax.

URI_FUNC() in UriParse.c in uriparser before 0.9.1 has an out-of-bounds read (in uriParse*Ex* functions) for an incomplete URI with an IPv6 address containing an embedded IPv4 address, such as a "//[::44.1" address.

An issue was discovered in uriparser before 0.9.0. UriQuery.c allows an out-of-bounds write via a uriComposeQuery* or uriComposeQueryEx* function because the '&' character is mishandled in certain contexts.
