MGASA-2024-0261 - Updated golang packages fix security vulnerability

Publication date: 11 Jul 2024
URL: https://advisories.mageia.org/MGASA-2024-0261.html
Type: security
Affected Mageia releases: 9
CVE: CVE-2024-24791

The net/http HTTP/1.1 client mishandled the case where a server responds
to a request with an "Expect: 100-continue" header with a
non-informational (200 or higher) status. This mishandling could leave a
client connection in an invalid state, where the next request sent on
the connection will fail. An attacker sending a request to a
net/http/httputil.ReverseProxy proxy can exploit this mishandling to
cause a denial of service by sending "Expect: 100-continue" requests
which elicit a non-informational response from the backend. Each such
request leaves the proxy with an invalid connection, and causes one
subsequent request using that connection to fail. (CVE-2024-24791)
