These look okay, although it doesn't appear that they've been resolved
in unstable yet?  If so, that really should be done first.  Once the
patches have been tested in unstable, we can then look again at applying
them to stable.

The security tracker indicates that this CVE hasn't yet been checked for
its applicability to and impact on Debian.  Have you confirmed with the
security team that they don't wish to handle this?

Looking at the upstream commits, should servers/slapd/main.c r1.279 be
included here?  As with the earlier patches, this should also be tested
in unstable before being applied to stable.
