CVE-2019-15226 (GCVE-0-2019-15226)

Vulnerability from cvelistv5 – Published: 2019-10-09 15:25 – Updated: 2024-08-05 00:42

Summary

Upon receiving each incoming request header data, Envoy will iterate over existing request headers to verify that the total size of the headers stays below a maximum limit. The implementation in versions 1.10.0 through 1.11.1 for HTTP/1.x traffic and all versions of Envoy for HTTP/2 traffic had O(n^2) performance characteristics. A remote attacker may craft a request that stays below the maximum request header size but consists of many thousands of small headers to consume CPU and result in a denial-of-service attack.

Severity

No CVSS data available.
