Several remote vulnerabilities have been discovered in OpenLDAP, a free implementation of the Lightweight Directory Access Protocol. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2007-5707     Thomas Sesselmann discovered that slapd could be crashed     by a malformed modify requests.

  - CVE-2007-5708     Toby Blade discovered that incorrect memory handling in     slapo-pcache could lead to denial of service through     crafted search requests.

  - CVE-2007-6698     It was discovered that a programming error in the     interface to the BDB storage backend could lead to     denial of service through crafted modify requests.

  - CVE-2008-0658     It was discovered that a programming error in the     interface to the BDB storage backend could lead to     denial of service through crafted modrdn requests.

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 (CVE-2007-5708).

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 (CVE-2007-6698) or modrdn (CVE-2008-0658) operations could cause slapd to crash.

The updated packages have been patched to correct these issues.

The remote host is affected by the vulnerability described in GLSA-200803-28 (OpenLDAP: Denial of Service vulnerabilities)

    The following errors have been discovered in OpenLDAP:
    Tony Blake discovered an error which exists within the normalisation of     'objectClasses' (CVE-2007-5707).
    Thomas Sesselmann reported that, when running as a proxy-caching server     the 'add_filter_attrs()' function in servers/slapd/overlay/pcache.c     does not correctly NULL terminate 'new_attrs' (CVE-2007-5708).
    A double-free bug exists in attrs_free() in the file     servers/slapd/back-bdb/modrdn.c, which was discovered by Jonathan     Clarke (CVE-2008-0658).
  Impact :

    A remote attacker can cause a Denial of Serivce by sending a malformed     'objectClasses' attribute, and via unknown vectors that prevent the     'new_attrs' array from being NULL terminated, and via a modrdn     operation with a NOOP (LDAP_X_NO_OPERATION) control.
  Workaround :

    There is no known workaround at this time.

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.
(CVE-2007-5707)

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. (CVE-2007-5708).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update fixes multiple flaws that could cause slapd to crash.
(CVE-2007-5707 / CVE-2007-5708)

BugTraq reports :

OpenLDAP is prone to multiple remote denial-of-service vulnerabilities because of an incorrect NULL-termination issue and a double-free issue.
