BIT-golang-2023-45288 / CVE-2023-45288 / GHSA-4v7x-pqxf-cx7m / GO-2024-2687
More information
#### Details An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header frames we will process before closing a connection. #### Severity Unknown #### References - [https://go.dev/issue/65051](https://go.dev/issue/65051) - [https://go.dev/cl/576155](https://go.dev/cl/576155) - [https://groups.google.com/g/golang-announce/c/YgW0sx8mN3M](https://groups.google.com/g/golang-announce/c/YgW0sx8mN3M) This data is provided by [OSV](https://osv.dev/vulnerability/GO-2024-2687) and the [Go Vulnerability Database](https://togithub.com/golang/vulndb) ([CC-BY 4.0](https://togithub.com/golang/vulndb#license)).net/http, x/net/http2: close connections when receiving too many headers
