A NULL pointer dereference was found in OpenLDAP server and was fixed in openldap 2.4.55, during a request for renaming RDNs. An unauthenticated attacker could remotely crash the slapd process by sending a specially crafted request, causing a Denial of Service. | 7.5 |
High |
|
11h47 +00:00 |
libldap in certain third-party OpenLDAP packages has a certificate-validation flaw when the third-party package is asserting RFC6125 support. It considers CN even when there is a non-matching subjectAltName (SAN). This is fixed in, for example, openldap-2.4.46-10.el8 in Red Hat Enterprise Linux. | 4.2 |
Medium |
|
16h07 +00:00 |
In filter.c in slapd in OpenLDAP before 2.4.50, LDAP search filters with nested boolean expressions can result in denial of service (daemon crash). | 7.5 |
High |
|
10h30 +00:00 |
An issue was discovered in OpenLDAP 2.x before 2.4.48. When using SASL authentication and session encryption, and relying on the SASL security layers in slapd access controls, it is possible to obtain access that would otherwise be denied via a simple bind for any identity covered in those ACLs. After the first SASL bind is completed, the sasl_ssf value is retained for all new non-SASL connections. Depending on the ACL configuration, this can affect different types of operations (searches, modifications, etc.). In other words, a successful authorization step completed by one user affects the authorization requirement for a different user. | 7.5 |
High |
|
10h19 +00:00 |
An issue was discovered in the server in OpenLDAP before 2.4.48. When the server administrator delegates rootDN (database admin) privileges for certain databases but wants to maintain isolation (e.g., for multi-tenant deployments), slapd does not properly stop a rootDN from requesting authorization as an identity from another database during a SASL bind or with a proxyAuthz (RFC 4370) control. (It is not a common configuration to deploy a system where the server administrator and a DB administrator enjoy different levels of trust.) | 4.9 |
Medium |
|
05h00 +00:00 |
contrib/slapd-modules/nops/nops.c in OpenLDAP through 2.4.45, when both the nops module and the memberof overlay are enabled, attempts to free a buffer that was allocated on the stack, which allows remote attackers to cause a denial of service (slapd crash) via a member MODDN operation. | 7.5 |
High |
|
16h00 +00:00 |
slapd in OpenLDAP 2.4.45 and earlier creates a PID file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for PID file modification before a root script executes a "kill `cat /pathname`" command, as demonstrated by openldap-initscript. | 4.7 |
Medium |
|
14h00 +00:00 |
servers/slapd/back-mdb/search.c in OpenLDAP through 2.4.44 is prone to a double free vulnerability. A user with access to search the directory can crash slapd by issuing a search including the Paged Results control with a page size of 0. | 6.5 |
Medium |
|
19h00 +00:00 |
The nss_parse_ciphers function in libraries/libldap/tls_m.c in OpenLDAP does not properly parse OpenSSL-style multi-keyword mode cipher strings, which might cause a weaker than intended cipher to be used and allow remote attackers to have unspecified impact via unknown vectors. | 7.5 |
High |
|
14h00 +00:00 |
The ber_get_next function in libraries/liblber/io.c in OpenLDAP 2.4.42 and earlier allows remote attackers to cause a denial of service (reachable assertion and application crash) via crafted BER data, as demonstrated by an attack against slapd. | 5 |
||
17h00 +00:00 |
The rwm overlay in OpenLDAP 2.4.23, 2.4.36, and earlier does not properly count references, which allows remote attackers to cause a denial of service (slapd crash) by unbinding immediately after a search request, which triggers rwm_conn_destroy to free the session context while it is being used by rwm_op_search. | 4.3 |
||
17h00 +00:00 |
slapd in OpenLDAP before 2.4.30 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via an LDAP search query with attrsOnly set to true, which causes empty attributes to be returned. | 2.6 |
||
23h00 +00:00 |
libraries/libldap/tls_m.c in OpenLDAP, possibly 2.4.31 and earlier, when using the Mozilla NSS backend, always uses the default cipher suite even when TLSCipherSuite is set, which might cause OpenLDAP to use weaker ciphers than intended and make it easier for remote attackers to obtain sensitive information. | 4.3 |
||
18h00 +00:00 |
Off-by-one error in the UTF8StringNormalize function in OpenLDAP 2.4.26 and earlier allows remote attackers to cause a denial of service (slapd crash) via a zero-length string that triggers a heap-based buffer overflow, as demonstrated using an empty postalAddressAttribute value in an LDIF entry. | 4 |
||
17h00 +00:00 |
libraries/libldap/tls_o.c in OpenLDAP 2.2 and 2.4, and possibly other versions, when OpenSSL is used, does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408. | 4.3 |
||
20h00 +00:00 |
The BDB backend for slapd in OpenLDAP before 2.3.36 allows remote authenticated users to cause a denial of service (crash) via a potentially-successful modify operation with the NOOP control set to critical, possibly due to a double free vulnerability. | 4 |
||
18h00 +00:00 |
OpenLDAP before 2.3.39 allows remote attackers to cause a denial of service (slapd crash) via an LDAP request with a malformed objectClasses attribute. NOTE: this has been reported as a double free, but the reports are inconsistent. | 7.1 |
||
18h00 +00:00 |
slapo-pcache (overlays/pcache.c) in slapd in OpenLDAP before 2.3.39, when running as a proxy-caching server, allocates memory using a malloc variant instead of calloc, which prevents an array from being initialized properly and might allow attackers to cause a denial of service (segmentation fault) via unknown vectors that prevent the array from being null terminated. | 7.1 |
||
23h00 +00:00 |
Buffer overflow in the krbv4_ldap_auth function in servers/slapd/kerberos.c in OpenLDAP 2.4.3 and earlier, when OpenLDAP is compiled with the --enable-kbind (Kerberos KBIND) option, allows remote attackers to execute arbitrary code via an LDAP bind request using the LDAP_AUTH_KRBV41 authentication method and long credential data. | 5.1 |
||
17h00 +00:00 |
OpenLDAP before 2.3.29 allows remote attackers to cause a denial of service (daemon crash) via LDAP BIND requests with long authcid names, which triggers an assertion failure. | 7.5 |
High |
|
02h00 +00:00 |
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. | 7.2 |
||
02h00 +00:00 |
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. | 5 |
||
02h00 +00:00 |
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). | 5 |
||
02h00 +00:00 |
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. | 7.5 |
||
04h00 +00:00 |
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. | 1.2 |
||
04h00 +00:00 |
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. | 7.5 |
||
04h00 +00:00 |
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. | 7.5 |
||
02h00 +00:00 |
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. | 5 |
||
02h00 +00:00 |
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. | 7.5 |
