I was thinking that since the signature check usually passes, the data
could be uncompressed into a cache, checked there, then copied into
place (assuming the check passes). If the data is capable of escaping
from that sandbox before being checked, that's a serious security bug in
the compression software that should be fixed in any case.

(Sorry for not responding in-thread. Gmane isn't updating its list of
