|---|---|---|---|---|
| CVE-2026-40355 | 1 Mit | 1 Kerberos 5 | 2026-10-15 | 5.9 Medium |
| In MIT Kerberos 5 (aka krb5) before 1.22.3, there is a NULL pointer dereference if an application calls gss_accept_sec_context() on a system with a NegoEx mechanism registered in /etc/gss/mech. An unauthenticated remote attacker can trigger this, causing the process to terminate in parse_nego_message. | ||||
| CVE-2022-42898 | 4 Heimdal Project, Mit, Redhat and 1 more | 10 Heimdal, Kerberos 5, Enterprise Linux and 7 more | 2026-10-14 | 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-2021-37750 | 6 Debian, Fedoraproject, Mit and 3 more | 6 Debian Linux, Fedora, Kerberos 5 and 3 more | 2026-10-14 | 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 | 5 Debian, Mit, Netapp and 2 more | 8 Debian Linux, Kerberos 5, Active Iq Unified Manager and 5 more | 2026-10-14 | 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 | 5 Fedoraproject, Mit, Netapp and 2 more | 13 Fedora, Kerberos 5, Active Iq Unified Manager and 10 more | 2026-10-14 | 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-2026-107708 | 1 Mit | 1 Kerberos 5 | 2026-10-14 | 4.9 Medium |
| MIT krb5 through 1.22.2 contains a NULL pointer dereference vulnerability in the KDC's get_pac_princ_with_realm() that returns success while leaving the client principal NULL on malformed names. A malicious or compromised cross-realm trusted KDC can send an S4U2Proxy request with a PAC carrying a malformed client name to crash krb5kdc and deny authentication. | ||||
| CVE-2026-107778 | 1 Mit | 1 Kerberos 5 | 2026-10-09 | 6.5 Medium |
| MIT Kerberos 5 (krb5) through 1.22.2 contains a NULL pointer dereference in make_cred_list() in rd_cred.c that allows authenticated Kerberos clients to crash services by sending mismatched KRB-CRED arrays. Attackers can send forwarded credentials with more tickets than ticket_info entries through gss_accept_sec_context() to crash GSS-API acceptor services, causing denial of service. | ||||
| CVE-2024-37371 | 3 Debian, Mit, Redhat | 9 Debian Linux, Kerberos 5, Enterprise Linux and 6 more | 2026-05-12 | 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 | 2 Mit, Redhat | 8 Kerberos 5, Enterprise Linux, Rhel Aus and 5 more | 2026-05-12 | 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-2026-40356 | 1 Mit | 1 Kerberos 5 | 2026-04-28 | 5.9 Medium |
| In MIT Kerberos 5 (aka krb5) before 1.22.3, there is an integer underflow and resultant out-of-bounds read if an application calls gss_accept_sec_context() on a system with a NegoEx mechanism registered in /etc/gss/mech. An unauthenticated remote attacker can trigger this, possibly causing the process to terminate in parse_message. | ||||
| CVE-2008-0947 | 2 Mit, Redhat | 2 Kerberos 5, Enterprise Linux | 2026-04-23 | N/A |
| Buffer overflow in the RPC library used by libgssrpc and kadmind in MIT Kerberos 5 (krb5) 1.4 through 1.6.3 allows remote attackers to execute arbitrary code by triggering a large number of open file descriptors. | ||||
| CVE-2007-4000 | 3 Fedoraproject, Mit, Redhat | 3 Fedora, Kerberos 5, Enterprise Linux | 2026-04-23 | 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-2009-0846 | 5 Apple, Canonical, Fedoraproject and 2 more | 9 Mac Os X, Ubuntu Linux, Fedora and 6 more | 2026-04-23 | 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-2007-3999 | 2 Mit, Redhat | 2 Kerberos 5, Enterprise Linux | 2026-04-23 | N/A |
| Stack-based buffer overflow in the svcauth_gss_validate function in lib/rpc/svc_auth_gss.c in the RPCSEC_GSS RPC library (librpcsecgss) in MIT Kerberos 5 (krb5) 1.4 through 1.6.2, as used by the Kerberos administration daemon (kadmind) and some third-party applications that use krb5, allows remote attackers to cause a denial of service (daemon crash) and probably execute arbitrary code via a long string in an RPC message. | ||||
| CVE-2006-6143 | 2 Canonical, Mit | 2 Ubuntu Linux, Kerberos 5 | 2026-04-23 | 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-2008-0063 | 8 Apple, Canonical, Debian and 5 more | 13 Mac Os X, Mac Os X Server, Ubuntu Linux and 10 more | 2026-04-23 | 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-2006-6144 | 1 Mit | 1 Kerberos 5 | 2026-04-23 | N/A |
| The "mechglue" abstraction interface of the GSS-API library for Kerberos 5 1.5 through 1.5.1, as used in Kerberos administration daemon (kadmind) and other products that use this library, allows remote attackers to cause a denial of service (crash) via unspecified vectors that cause mechglue to free uninitialized pointers. | ||||
| CVE-2007-4743 | 2 Mit, Redhat | 2 Kerberos 5, Enterprise Linux | 2026-04-23 | N/A |
| The original patch for CVE-2007-3999 in svc_auth_gss.c in the RPCSEC_GSS RPC library in MIT Kerberos 5 (krb5) 1.4 through 1.6.2, as used by the Kerberos administration daemon (kadmind) and other applications that use krb5, does not correctly check the buffer length in some environments and architectures, which might allow remote attackers to conduct a buffer overflow attack. | ||||
| CVE-2008-0062 | 5 Canonical, Debian, Fedoraproject and 2 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2026-04-23 | 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-2007-5894 | 1 Mit | 1 Kerberos 5 | 2026-04-23 | N/A |
| 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. | ||||
