Vulnerability from github – Published: 2021-08-25 21:01 – Updated: 2023-06-13 18:21

Summary

Integer Overflow/Infinite Loop in the http crate

Details

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 sufficiently large number in release mode.

If the map was 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 0.1.20 release of http crate.

Severity

7.5 (High)

RUSTSEC-2019-0033 (CVE-2019-25008)

Vulnerability from osv_rustsec – Published: 2019-11-16 12:00 – Updated: 2023-06-13 13:10 – Source website

Summary

Integer Overflow in HeaderMap::reserve() can cause Denial of Service

Details

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 sufficiently large number in release mode.

If the map was 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 0.1.20 release of http crate.
