OpenldapCVEs & Vulnerabilities

Stack-based buffer overflow in st.c in slurpd for OpenLDAP before 2.3.22 might allow attackers to execute arbitrary code via a long hostname.

Untrusted search path vulnerability in OpenLDAP before 2.2.28-r3 on Gentoo Linux allows local users in the portage group to gain privileges via a malicious shared object in the Portage temporary build directory, which is part of the RUNPATH.

pam_ldap and nss_ldap, when used with OpenLDAP and connecting to a slave using TLS, does not use TLS for the subsequent connection if the client is referred to a master, which may cause a password to be sent in cleartext and allows remote attackers to sniff the password.

Memory leak in the back-bdb backend for OpenLDAP 2.1.12 and earlier allows remote attackers to cause a denial of service (memory consumption).

OpenLDAP 1.0 through 2.1.19, as used in Apple Mac OS 10.3.4 and 10.3.5 and possibly other operating systems, may allow certain authentication schemes to use hashed (crypt) passwords in the userPassword attribute as if they were plaintext passwords, which allows remote attackers to re-use hashed passwords without decrypting them.

ldbm_back_exop_passwd in the back-ldbm backend in passwd.c for OpenLDAP 2.1.12 and earlier, when the slap_passwd_parse function does not return LDAP_SUCCESS, attempts to free an uninitialized pointer, which allows remote attackers to cause a denial of service (segmentation fault).

slapd in OpenLDAP2 (OpenLDAP 2) 2.2.0 and earlier allows local users to overwrite arbitrary files via a race condition during the creation of a log file for rejected replication requests.

Multiple buffer overflows in OpenLDAP2 (OpenLDAP 2) 2.2.0 and earlier allow remote attackers to execute arbitrary code via (1) long -t or -r parameters to slurpd, (2) a malicious ldapfilter.conf file that is not properly handled by getfilter functions, (3) a malicious ldaptemplates.conf that causes an overflow in libldap, (4) a certain access control list that causes an overflow in slapd, or (5) a long generated filename for logging rejected replication requests.

OpenLDAP2 (OpenLDAP 2) 2.2.0 and earlier allows remote or local attackers to execute arbitrary code when libldap reads the .ldaprc file within applications that are running with extra privileges.

slapd in OpenLDAP 2.0 through 2.0.19 allows local users, and anonymous users before 2.0.8, to conduct a "replace" action on access controls without any values, which causes OpenLDAP to delete non-mandatory attributes that would otherwise be protected by ACLs.

slapd in OpenLDAP 1.x before 1.2.12, and 2.x before 2.0.8, allows remote attackers to cause a denial of service (crash) via an invalid Basic Encoding Rules (BER) length field.

OpenLDAP 1.2.11 and earlier improperly installs the ud binary with group write permissions, which could allow any user in that group to replace the binary with a Trojan horse.

Linux OpenLDAP server allows local users to modify arbitrary files via a symlink attack.
