The Debian bug is really light on details, so here is the git commit that fixes this: http://nbd.git.sourceforge.net/git/gitweb.cgi?p=nbd/nbd;a=commitdiff;h=ebbbe0b3ce5393fa42a259f5e03d549508586aaa But I don't see any evidence that this _only_ affects 2.9.21. Are we sure that it doesn't affect earlier versions? The reporter doesn't indicate one way or the other. CC'ing Wouter for clarification. -- Vincent Danen / Red Hat Security Response Team
