| CVE-2024-37371 | 2 Debian, Mit | 2 Debian Linux, Kerberos 5 | 2024-09-18 | N/A | 9.1 CRITICAL |
| In MIT Kerberos 5 (aka krb5) before 1.21.3, an attacker can cause invalid memory reads during GSS message token handling by sending message tokens with invalid length fields. | |||||
| CVE-2024-37370 | 1 Mit | 1 Kerberos 5 | 2024-08-27 | N/A | 7.5 HIGH |
| In MIT Kerberos 5 (aka krb5) before 1.21.3, an attacker can modify the plaintext Extra Count field of a confidential GSS krb5 wrap token, causing the unwrapped token to appear truncated to the application. | |||||
| CVE-2007-5894 | 1 Mit | 1 Kerberos 5 | 2024-08-07 | 9.3 HIGH | N/A |
| ** DISPUTED ** The reply function in ftpd.c in the gssftp ftpd in MIT Kerberos 5 (krb5) does not initialize the length variable when auth_type has a certain value, which has unknown impact and remote authenticated attack vectors. NOTE: the original disclosure misidentifies the conditions under which the uninitialized variable is used. NOTE: the vendor disputes this issue, stating " The 'length' variable is only uninitialized if 'auth_type' is neither the 'KERBEROS_V4' nor 'GSSAPI'; this condition cannot occur in the unmodified source code." | |||||
| CVE-2018-5730 | 4 Debian, Fedoraproject, Mit and 1 more | 6 Debian Linux, Fedora, Kerberos 5 and 3 more | 2024-05-23 | 5.5 MEDIUM | 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-2018-5729 | 4 Debian, Fedoraproject, Mit and 1 more | 6 Debian Linux, Fedora, Kerberos 5 and 3 more | 2024-05-23 | 6.5 MEDIUM | 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-2006-6143 | 2 Canonical, Mit | 2 Ubuntu Linux, Kerberos 5 | 2024-02-09 | 9.3 HIGH | N/A |
| The RPC library in Kerberos 5 1.4 through 1.4.4, and 1.5 through 1.5.1, as used in Kerberos administration daemon (kadmind) and other products that use this library, calls an uninitialized function pointer in freed memory, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors. | |||||
| CVE-2007-4000 | 2 Fedoraproject, Mit | 2 Fedora, Kerberos 5 | 2024-02-09 | 8.5 HIGH | N/A |
| The kadm5_modify_policy_internal function in lib/kadm5/srv/svr_policy.c in the Kerberos administration daemon (kadmind) in MIT Kerberos 5 (krb5) 1.5 through 1.6.2 does not properly check return values when the policy does not exist, which might allow remote authenticated users with the "modify policy" privilege to execute arbitrary code via unspecified vectors that trigger a write to an uninitialized pointer. | |||||
| CVE-2007-2442 | 3 Canonical, Debian, Mit | 3 Ubuntu Linux, Debian Linux, Kerberos 5 | 2024-02-09 | 10.0 HIGH | N/A |
| The gssrpc__svcauth_gssapi function in the RPC library in MIT Kerberos 5 (krb5) 1.6.1 and earlier might allow remote attackers to execute arbitrary code via a zero-length RPC credential, which causes kadmind to free an uninitialized pointer during cleanup. | |||||
| CVE-2009-0846 | 5 Apple, Canonical, Fedoraproject and 2 more | 9 Mac Os X, Ubuntu Linux, Fedora and 6 more | 2024-02-09 | 10.0 HIGH | N/A |
| The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 (aka krb5) before 1.6.4 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer. | |||||
| CVE-2008-0062 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2024-02-09 | 9.3 HIGH | 9.8 CRITICAL |
| KDC in MIT Kerberos 5 (krb5kdc) does not set a global variable for some krb4 message types, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted messages that trigger a NULL pointer dereference or double-free. | |||||
| CVE-2008-0063 | 7 Apple, Canonical, Debian and 4 more | 11 Mac Os X, Mac Os X Server, Ubuntu Linux and 8 more | 2024-02-09 | 4.3 MEDIUM | 7.5 HIGH |
| The Kerberos 4 support in KDC in MIT Kerberos 5 (krb5kdc) does not properly clear the unused portion of a buffer when generating an error message, which might allow remote attackers to obtain sensitive information, aka "Uninitialized stack values." | |||||
| CVE-2023-39975 | 1 Mit | 1 Kerberos 5 | 2024-02-05 | N/A | 8.8 HIGH |
| kdc/do_tgs_req.c in MIT Kerberos 5 (aka krb5) 1.21 before 1.21.2 has a double free that is reachable if an authenticated user can trigger an authorization-data handling failure. Incorrect data is copied from one ticket to another. | |||||
| CVE-2023-36054 | 1 Mit | 1 Kerberos 5 | 2024-02-05 | N/A | 6.5 MEDIUM |
| lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) before 1.20.2 and 1.21.x before 1.21.1 frees an uninitialized pointer. A remote authenticated user can trigger a kadmind crash. This occurs because _xdr_kadm5_principal_ent_rec does not validate the relationship between n_key_data and the key_data array count. | |||||
| CVE-2022-42898 | 3 Heimdal Project, Mit, Samba | 3 Heimdal, Kerberos 5, Samba | 2024-02-04 | N/A | 8.8 HIGH |
| PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has "a similar bug." | |||||
| CVE-2022-39028 | 3 Debian, Gnu, Mit | 3 Debian Linux, Inetutils, Kerberos 5 | 2024-02-04 | N/A | 7.5 HIGH |
| telnetd in GNU Inetutils through 2.3, MIT krb5-appl through 1.0.3, and derivative works has a NULL pointer dereference via 0xff 0xf7 or 0xff 0xf8. In a typical installation, the telnetd application would crash but the telnet service would remain available through inetd. However, if the telnetd application has many crashes within a short time interval, the telnet service would become unavailable after inetd logs a "telnet/tcp server failing (looping), service terminated" error. 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-2021-37750 | 5 Debian, Fedoraproject, Mit and 2 more | 5 Debian Linux, Fedora, Kerberos 5 and 2 more | 2024-02-04 | 4.0 MEDIUM | 6.5 MEDIUM |
| The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.5 and 1.19.x before 1.19.3 has a NULL pointer dereference in kdc/do_tgs_req.c via a FAST inner body that lacks a server field. | |||||
| CVE-2021-36222 | 4 Debian, Mit, Netapp and 1 more | 7 Debian Linux, Kerberos 5, Active Iq Unified Manager and 4 more | 2024-02-04 | 5.0 MEDIUM | 7.5 HIGH |
| ec_verify in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.4 and 1.19.x before 1.19.2 allows remote attackers to cause a NULL pointer dereference and daemon crash. This occurs because a return value is not properly managed in a certain situation. | |||||
| CVE-2020-28196 | 4 Fedoraproject, Mit, Netapp and 1 more | 11 Fedora, Kerberos 5, Active Iq Unified Manager and 8 more | 2024-02-04 | 5.0 MEDIUM | 7.5 HIGH |
| MIT Kerberos 5 (aka krb5) before 1.17.2 and 1.18.x before 1.18.3 allows unbounded recursion via an ASN.1-encoded Kerberos message because the lib/krb5/asn.1/asn1_encode.c support for BER indefinite lengths lacks a recursion limit. | |||||
| CVE-2019-14844 | 2 Fedoraproject, Mit | 2 Fedora, Kerberos 5 | 2024-02-04 | 5.0 MEDIUM | 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. | |||||
| CVE-2017-7562 | 2 Mit, Redhat | 5 Kerberos 5, Enterprise Linux, Enterprise Linux Desktop and 2 more | 2024-02-04 | 4.0 MEDIUM | 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. | |||||
