Description Laura Pardo 2019-01-14 16:58:11 UTC
A flaw was found in uriparser before version 0.9.1. An Out-of-bounds read in uriParse*Ex* for incomplete URIs with IPv6 addresses with embedded IPv4 address, e.g. "//[::44.1"; mitigated if passed parameter <afterLast> points to readable memory containing a '\0' byte.
