Detailsinfo

A vulnerability was found in Google Go (Programming Language Software) (affected version unknown) and classified as problematic. This issue affects an unknown functionality of the component net-http. The manipulation with an unknown input leads to a memory allocation vulnerability. Using CWE to declare the problem leads to CWE-789. The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated. Impacted is availability. The summary by CVE is:

An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.

The weakness was published 12/09/2022. It is possible to read the advisory at go.dev. The identification of this vulnerability is CVE-2022-41717 since 09/28/2022. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 11/30/2025).
