Synopsis ========
A flaw in OpenLDAP allows remote unauthenticated attackers to cause a Denial of Service.
Background ==========
OpenLDAP is a suite of LDAP-related applications and development tools.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-nds/openldap < 2.3.27-r3 >= 2.3.27-r3 *>= 2.2.28-r5 *>= 2.1.30-r8
Description ===========
Evgeny Legerov has discovered that the truncation of an incoming authcid longer than 255 characters and ending with a space as the 255th character will lead to an improperly computed name length. This will trigger an assert in the libldap code.
Impact ======
By sending a BIND request with a specially crafted authcid parameter to an OpenLDAP service, a remote attacker can cause the service to crash.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All OpenLDAP users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose "net-nds/openldap"
References ==========
