CVE-2015-8631 | 5 Debian, Mit, Opensuse and 2 more | 12 Debian Linux, Kerberos 5, Leap and 9 more | 2024-08-06 | 6.5 Medium |
Multiple memory leaks in kadmin/server/server_stubs.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 allow remote authenticated users to cause a denial of service (memory consumption) via a request specifying a NULL principal name. | ||||
CVE-2015-2697 | 6 Canonical, Debian, Mit and 3 more | 9 Ubuntu Linux, Debian Linux, Kerberos 5 and 6 more | 2024-08-06 | N/A |
The build_principal_va function in lib/krb5/krb/bld_princ.c in MIT Kerberos 5 (aka krb5) before 1.14 allows remote authenticated users to cause a denial of service (out-of-bounds read and KDC crash) via an initial '\0' character in a long realm field within a TGS request. | ||||
CVE-2015-2698 | 1 Mit | 1 Kerberos 5 | 2024-08-06 | N/A |
The iakerb_gss_export_sec_context function in lib/gssapi/krb5/iakerb.c in MIT Kerberos 5 (aka krb5) 1.14 pre-release 2015-09-14 improperly accesses a certain pointer, which allows remote authenticated users to cause a denial of service (memory corruption) or possibly have unspecified other impact by interacting with an application that calls the gss_export_sec_context function. NOTE: this vulnerability exists because of an incorrect fix for CVE-2015-2696. | ||||
CVE-2015-2695 | 6 Canonical, Debian, Mit and 3 more | 9 Ubuntu Linux, Debian Linux, Kerberos 5 and 6 more | 2024-08-06 | N/A |
lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) before 1.14 relies on an inappropriate context handle, which allows remote attackers to cause a denial of service (incorrect pointer read and process crash) via a crafted SPNEGO packet that is mishandled during a gss_inquire_context call. | ||||
CVE-2015-2696 | 5 Canonical, Debian, Mit and 2 more | 8 Ubuntu Linux, Debian Linux, Kerberos 5 and 5 more | 2024-08-06 | N/A |
lib/gssapi/krb5/iakerb.c in MIT Kerberos 5 (aka krb5) before 1.14 relies on an inappropriate context handle, which allows remote attackers to cause a denial of service (incorrect pointer read and process crash) via a crafted IAKERB packet that is mishandled during a gss_inquire_context call. | ||||
CVE-2015-2694 | 2 Mit, Redhat | 2 Kerberos 5, Enterprise Linux | 2024-08-06 | N/A |
The kdcpreauth modules in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.2 do not properly track whether a client's request has been validated, which allows remote attackers to bypass an intended preauthentication requirement by providing (1) zero bytes of data or (2) an arbitrary realm name, related to plugins/preauth/otp/main.c and plugins/preauth/pkinit/pkinit_srv.c. | ||||
CVE-2016-3119 | 3 Mit, Opensuse, Redhat | 4 Kerberos 5, Leap, Opensuse and 1 more | 2024-08-05 | N/A |
The process_db_args function in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the LDAP KDB module in kadmind in MIT Kerberos 5 (aka krb5) through 1.13.4 and 1.14.x through 1.14.1 mishandles the DB argument, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request to modify a principal. | ||||
CVE-2016-3120 | 2 Mit, Redhat | 2 Kerberos 5, Enterprise Linux | 2024-08-05 | N/A |
The validate_as_request function in kdc_util.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.13.6 and 1.4.x before 1.14.3, when restrict_anonymous_to_tgt is enabled, uses an incorrect client data structure, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an S4U2Self request. | ||||
CVE-2017-15088 | 1 Mit | 1 Kerberos 5 | 2024-08-05 | 9.8 Critical |
plugins/preauth/pkinit/pkinit_crypto_openssl.c in MIT Kerberos 5 (aka krb5) through 1.15.2 mishandles Distinguished Name (DN) fields, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) in situations involving untrusted X.509 data, related to the get_matching_data and X509_NAME_oneline_ex functions. NOTE: this has security relevance only in use cases outside of the MIT Kerberos distribution, e.g., the use of get_matching_data in KDC certauth plugin code that is specific to Red Hat. | ||||
CVE-2017-11462 | 2 Fedoraproject, Mit | 2 Fedora, Kerberos 5 | 2024-08-05 | N/A |
Double free vulnerability in MIT Kerberos 5 (aka krb5) allows attackers to have unspecified impact via vectors involving automatic deletion of security contexts on error. | ||||
CVE-2017-11368 | 3 Fedoraproject, Mit, Redhat | 4 Fedora, Kerberos, Kerberos 5 and 1 more | 2024-08-05 | N/A |
In MIT Kerberos 5 (aka krb5) 1.7 and later, an authenticated attacker can cause a KDC assertion failure by sending invalid S4U2Self or S4U2Proxy requests. | ||||
CVE-2017-7562 | 2 Mit, Redhat | 5 Kerberos 5, Enterprise Linux, Enterprise Linux Desktop and 2 more | 2024-08-05 | 6.5 Medium |
An authentication bypass flaw was found in the way krb5's certauth interface before 1.16.1 handled the validation of client certificates. A remote attacker able to communicate with the KDC could potentially use this flaw to impersonate arbitrary principals under rare and erroneous circumstances. | ||||
CVE-2018-20217 | 3 Debian, Mit, Redhat | 4 Debian Linux, Kerberos, Ansible Tower and 1 more | 2024-08-05 | 5.3 Medium |
A Reachable Assertion issue was discovered in the KDC in MIT Kerberos 5 (aka krb5) before 1.17. If an attacker can obtain a krbtgt ticket using an older encryption type (single-DES, triple-DES, or RC4), the attacker can crash the KDC by making an S4U2Self request. | ||||
CVE-2018-5729 | 4 Debian, Fedoraproject, Mit and 1 more | 7 Debian Linux, Fedora, Kerberos 5 and 4 more | 2024-08-05 | 4.7 Medium |
MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to cause a denial of service (NULL pointer dereference) or bypass a DN container check by supplying tagged data that is internal to the database module. | ||||
CVE-2018-5730 | 4 Debian, Fedoraproject, Mit and 1 more | 7 Debian Linux, Fedora, Kerberos 5 and 4 more | 2024-08-05 | 3.8 Low |
MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to circumvent a DN containership check by supplying both a "linkdn" and "containerdn" database argument, or by supplying a DN string which is a left extension of a container DN string but is not hierarchically within the container DN. | ||||
CVE-2018-5709 | 1 Mit | 1 Kerberos | 2024-08-05 | N/A |
An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. There is a variable "dbentry->n_key_data" in kadmin/dbutil/dump.c that can store 16-bit data but unknowingly the developer has assigned a "u4" variable to it, which is for 32-bit data. An attacker can use this vulnerability to affect other artifacts of the database as we know that a Kerberos database dump file contains trusted data. | ||||
CVE-2018-5710 | 1 Mit | 1 Kerberos | 2024-08-05 | N/A |
An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. The pre-defined function "strlen" is getting a "NULL" string as a parameter value in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the Key Distribution Center (KDC), which allows remote authenticated users to cause a denial of service (NULL pointer dereference) via a modified kadmin client. | ||||
CVE-2019-25017 | 1 Mit | 1 Krb5-appl | 2024-08-05 | 5.9 Medium |
An issue was discovered in rcp in MIT krb5-appl through 1.0.3. Due to the rcp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the rcp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious rcp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rcp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file). This issue is similar to CVE-2019-6111 and CVE-2019-7283. NOTE: MIT krb5-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8. | ||||
CVE-2019-25018 | 1 Mit | 1 Krb5-appl | 2024-08-05 | 7.5 High |
In the rcp client in MIT krb5-appl through 1.0.3, malicious servers could bypass intended access restrictions via the filename of . or an empty filename, similar to CVE-2018-20685 and CVE-2019-7282. The impact is modifying the permissions of the target directory on the client side. NOTE: MIT krb5-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8. | ||||
CVE-2019-14844 | 2 Fedoraproject, Mit | 2 Fedora, Kerberos 5 | 2024-08-05 | 7.5 High |
A flaw was found in, Fedora versions of krb5 from 1.16.1 to, including 1.17.x, in the way a Kerberos client could crash the KDC by sending one of the RFC 4556 "enctypes". A remote unauthenticated user could use this flaw to crash the KDC. |
