Description Jan Lieskovsky 2011-02-24 07:37:36 EST

Common Vulnerabilities and Exposures assigned an identifier CVE-2011-1067 to
the following vulnerability:

slapd (aka ns-slapd) in 389 Directory Server before 1.2.8.a2 does not
properly manage the c_timelimit field of the connection table element,
which allows remote attackers to cause a denial of service (daemon
outage) via Simple Paged Results connections, as demonstrated by using
multiple processes to replay TCP sessions, a different vulnerability
than CVE-2011-0019.

Rich, Noriko, did this affect RH Directory Server 8?

Yes, and we released an errata to fix this in rhds 8.2

I don't see the patch linked in comment #1 applied in the latest 8.2.4 packages from RHSA-2011:0293.  Part of it is not even applicable (there's no pagedresults_cleanup function).

Right.  This "Bug 668619 - slapd stops responding" was introduced by a preceding fix for 'Bug 567282 - server can not abandon searchRequest of "simple paged results"', which is not included in RHDS8.2.  Thus, 8.2 does not have this issue.

Comment 5 Tomas Hoger 2011-04-19 12:58:57 EDT

Thank you, Noriko!

Statement:

Not vulnerable. This issue did not affect Red Hat Directory Server 8 packages.
