openldap - potential code execution

Two remote vulnerabilities have been discovered in OpenLDAP. The
Common Vulnerabilities and Exposures project identifies the following
problems:

• CVE-2010-0211
  The slap_modrdn2mods function in modrdn.c in OpenLDAP 2.4.22 does
  not check the return value of a call to the smr_normalize
  function, which allows remote attackers to cause a denial of
  service (segmentation fault) and possibly execute arbitrary code
  via a modrdn call with an RDN string containing invalid UTF-8
  sequences.
• CVE-2010-0212
  OpenLDAP 2.4.22 allows remote attackers to cause a denial of
  service (crash) via a modrdn call with a zero-length RDN
  destination string.

For the stable distribution (lenny), this problem has been fixed in
version 2.4.11-1+lenny2. (The missing update for the mips
architecture will be provided soon.)

For the unstable distribution (sid), this problem has been fixed in
version 2.4.23-1.

We recommend that you upgrade your openldap packages.
