QID 980348: Java (maven) Security Update for io.netty:netty-codec-http2 (GHSA-f256-j965-7f32)

Security update has been released for io.netty:netty-codec-http2 to fix the vulnerability.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

The content-length header is not correctly validated if the request only use a single Http2HeaderFrame with the endStream set to to true. This could lead to request smuggling if the request is proxied to a remote peer and translated to HTTP/1.1

This is a followup of https://github.com/netty/netty/security/advisories/GHSA-wm47-8v5p-wjpj which did miss to fix this one case.

CVSS V3 rated as Medium - 5.9 severity.

CVSS V2 rated as Medium - 4.3 severity.

Solution

This was fixed as part of 4.1.61.FinalWorkaround:
Validation can be done by the user before proxy the request by validating the header.
