[Eclipse Jetty] GzipHandler memory leak
The Eclipse Foundation is a Common Vulnerabilities and Exposures (CVE) Numbering Authority. This issue it used to request and track the progress of the assignment of a CVE for a vulnerability in the project code for an Eclipse open source project.
Basic information
Project name: Eclipse Jetty
Project id: rt/jetty
Request type: reservation
Versions affected: >=12.0.0 <=12.0.31; >=12.1.0 <=12.1.5
Common Weakness Enumeration:
- CWE-400
- CWE-401
Common Vulnerability Scoring System: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary:
In Eclipse Jetty, versions 12.0.0-12.0.31 and 12.1.0-12.0.5, class GzipHandler exposes a vulnerability when a compressed HTTP request, with Content-Encoding: gzip, is processed and the corresponding response is not compressed.
This happens because the JDK Inflater is allocated for decompressing the request, but it is not released because the release mechanism is tied to the compressed response.
In this case, since the response is not compressed, the release mechanism does not trigger, causing the leak.
