Advisories MDVSA-2010:142: openldap

[paul]

Multiple vulnerabilities has been discovered and corrected in openldap:

 

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, which triggers a free

of an invalid, uninitialized pointer in the slap_mods_free function, as

demonstrated using the Codenomicon LDAPv3 test suite (CVE-2010-0211).

 

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,

which is not properly handled by the smr_normalize function and

triggers a NULL pointer dereference in the IA5StringNormalize function

in schema_init.c, as demonstrated using the Codenomicon LDAPv3 test

suite (CVE-2010-0212).
