Summary

CVE-2023-36478 affects Eclipse Jetty versions 11.0.0 through 11.0.15, 10.0.0 through 10.0.15, and 9.0.0 through 9.4.52. The vulnerability stems from an integer overflow in `MetaDataBuilder.checkSize`, which is responsible for determining the size limit of HTTP/2 HPACK header values. When a large user-entered size is multiplied by 4, an overflow occurs, and the check for a negative size is bypassed. Subsequently, a large buffer is allocated on the server, leading to a potential remote denial of service attack. This issue has been rectified in versions 11.0.16, 10.0.16, and 9.4.53, and no workarounds are currently available.
