Description Matteo Signorini 2026-07-21 11:55:33 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

SSH Agent servers do not validate the size of messages when processing new identity requests, which may cause the program to panic if the message is malformed due to an out of bounds read.
Comment 1 Dave Dykstra 2026-07-21 14:29:33 UTC 
This is a very old vulnerability, a bogus notification.  Apptainer long ago updated past this vulnerable version v0.45.0, and the current released apptainer.spec says 

Provides: bundled(golang(golang.org/x/crypto)) = v0.50.0

Besides that, Apptainer doesn't even use the impacted module golang.org/x/crypto/ssh/agent.
