CVE-2016-6580 (GCVE-0-2016-6580)

Vulnerability from cvelistv5 – Published: 2017-01-10 15:00 – Updated: 2024-08-06 01:36

Summary

A HTTP/2 implementation built using any version of the Python priority library prior to version 1.2.0 could be targeted by a malicious peer by having that peer assign priority information for every possible HTTP/2 stream ID. The priority tree would happily continue to store the priority information for each stream, and would therefore allocate unbounded amounts of memory. Attempting to actually use a tree like this would also cause extremely high CPU usage to maintain the tree.

Severity

No CVSS data available.
