+# Enter a short-form description of the vulnerability here (mandatory)
+description = """
+`HeaderMap::reserve()` used `usize::next_power_of_two()` to calculate the increased capacity.
+However, `next_power_of_two()` silently overflows to 0 if given a sufficently large number
+in release mode.
+
+If the map is not empty when the overflow happens,
+the library will invoke `self.grow(0)` and start infinite probing.
+This allows an attacker who controls the argument to `reserve()`
+to cause a potential denial of service (DoS).
+
+The flaw was corrected in 0.2.0 release of `http` crate.
