Debian DSA-2077-1 : openldap - several vulnerabilities

medium Nessus Plugin ID 48220

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the openldap packages.

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.)
