Overview
Affected versions of this package are vulnerable to Out-of-bounds Read in the urldecode function when a signed char is passed to ctype functions such as isxdigit. An attacker can cause a denial of service by providing input that leads to accessing an array with a negative offset on systems with default signed char and optimized table-lookup ctype functions, such as NetBSD.
