NVD Description

Note: Versions mentioned in the description apply only to the upstream unleash-fips package and not the unleash-fips package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

compression is a Node.js and Express compression middleware. In versions before 1.8.2, when a client aborts the connection while a compressed response is still being sent, the zlib stream created to compress that response is never destroyed, so each aborted compressed response leaks its native zlib memory. A remote unauthenticated attacker can repeatedly open requests and disconnect early, exhausting the available memory and crashing the server. All applications using compression are affected. The issue is fixed in compression 1.8.2, and users should upgrade to 1.8.2 or later.
