Mandriva Linux Security Advisory - A vulnerability was found in slapo-pcache in slapd of OpenLDAP prior to 2.3.39 when running as a proxy-caching server. It would allocate memory using a malloc variant rather than calloc, which prevented an array from being properly initialized and could possibly allow attackers to cause a denial of service. Two vulnerabilities were found in how slapd handled modify (prior to 2.3.26) and modrdn (prior to 2.3.29) requests with NOOP control on objects stored in the BDB backend. An authenticated user with permission to perform modify or modrdn operations could cause slapd to crash.

Ubuntu Security Notice 551-1 - Thomas Sesselmann discovered that the OpenLDAP slapd server did not properly handle certain modify requests. A remote attacker could send malicious modify requests to the server and cause a denial of service. Toby Blake discovered that slapd did not properly terminate an array while running as a proxy-caching server. A remote attacker may be able to send crafted search requests to the server and cause a denial of service. This issue only affects Ubuntu 7.04 and 7.10.
