CVE-2011-4079 Open this link in a new tabHow to fix?
Upgrade Debian:8 openldap to version 2.4.28-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openldap package and not the openldap package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
Off-by-one error in the UTF8StringNormalize function in OpenLDAP 2.4.26 and earlier allows remote attackers to cause a denial of service (slapd crash) via a zero-length string that triggers a heap-based buffer overflow, as demonstrated using an empty postalAddressAttribute value in an LDIF entry.
