NewCVE-2026-115823 (opens in a new tab)How to fix?
There is no fixed version for Debian:12 starman.
NVD Description
Note: Versions mentioned in the description apply only to the upstream starman package and not the starman package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
Starman versions before 0.4019 for Perl send response bodies for HEAD requests, desynchronizing responses on keep-alive connections.
For a HEAD request Starman omits chunked framing but still writes the body returned by the application, on both the array and streaming response paths. Responses with a 1xx, 204 or 304 status also carry the body.
On a keep-alive or pipelined connection the client reads those bytes as the start of the next response. A front-end proxy that reuses upstream connections may then pair responses with the wrong requests.
