Summary

openrsync through 0.5.0, as used in OpenBSD through 7.8 and on other platforms, allows a client to cause a server SIGSEGV by specifying a length of zero for block data, because the relationship between p->rem and p->len is not checked.

Server crash (SIGSEGV) could lead to disruption of the synchronization service, potentially affecting systems that rely on openrsync.

Recommendation

Update openrsync to a patched version. If not available, restrict access to the service and monitor its operation.
