CVE-2017-11462 2 Fedoraproject, Mit 2 Fedora, Kerberos 5 2025-04-20 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 2025-04-20 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-2017-15088 1 Mit 1 Kerberos 5 2025-04-20 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-2022-42898 4 Heimdal Project, Mit, Redhat and 1 more 10 Heimdal, Kerberos 5, Enterprise Linux and 7 more 2025-04-14 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-2014-9422 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2025-04-12 N/A
The check_rpcsec_auth function in kadmin/server/kadm_rpc_svc.c in kadmind in MIT Kerberos 5 (aka krb5) through 1.11.5, 1.12.x through 1.12.2, and 1.13.x before 1.13.1 allows remote authenticated users to bypass a kadmin/* authorization check and obtain administrative access by leveraging access to a two-component principal with an initial "kadmind" substring, as demonstrated by a "ka/x" principal.
CVE-2015-2696 5 Canonical, Debian, Mit and 2 more 8 Ubuntu Linux, Debian Linux, Kerberos 5 and 5 more 2025-04-12 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-2015-2697 6 Canonical, Debian, Mit and 3 more 9 Ubuntu Linux, Debian Linux, Kerberos 5 and 6 more 2025-04-12 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-2014-5351 1 Mit 1 Kerberos 5 2025-04-12 N/A
The kadm5_randkey_principal_3 function in lib/kadm5/srv/svr_principal.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13 sends old keys in a response to a -randkey -keepold request, which allows remote authenticated users to forge tickets by leveraging administrative access.
CVE-2014-5354 1 Mit 2 Kerberos, Kerberos 5 2025-04-12 N/A
plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.1, when the KDC uses LDAP, allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) by creating a database entry for a keyless principal, as demonstrated by a kadmin "add_principal -nokey" or "purgekeys -all" command.
CVE-2014-5352 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2025-04-12 N/A
The krb5_gss_process_context_token function in lib/gssapi/krb5/process_context_token.c in the libgssapi_krb5 library in MIT Kerberos 5 (aka krb5) through 1.11.5, 1.12.x through 1.12.2, and 1.13.x before 1.13.1 does not properly maintain security-context handles, which allows remote authenticated users to cause a denial of service (use-after-free and double free, and daemon crash) or possibly execute arbitrary code via crafted GSSAPI traffic, as demonstrated by traffic to kadmind.
CVE-2014-4344 3 Debian, Mit, Redhat 7 Debian Linux, Kerberos 5, Enterprise Linux and 4 more 2025-04-12 N/A
The acc_ctx_cont function in the SPNEGO acceptor in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) 1.5.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an empty continuation token at a certain point during a SPNEGO negotiation.
CVE-2014-5353 7 Canonical, Debian, Fedoraproject and 4 more 13 Ubuntu Linux, Debian Linux, Fedora and 10 more 2025-04-12 N/A
The krb5_ldap_get_password_policy_from_dn function in plugins/kdb/ldap/libkdb_ldap/ldap_pwd_policy.c in MIT Kerberos 5 (aka krb5) before 1.13.1, when the KDC uses LDAP, allows remote authenticated users to cause a denial of service (daemon crash) via a successful LDAP query with no results, as demonstrated by using an incorrect object type for a password policy.
CVE-2014-9423 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2025-04-12 N/A
The svcauth_gss_accept_sec_context function in lib/rpc/svc_auth_gss.c in MIT Kerberos 5 (aka krb5) 1.11.x through 1.11.5, 1.12.x through 1.12.2, and 1.13.x before 1.13.1 transmits uninitialized interposer data to clients, which allows remote attackers to obtain sensitive information from process heap memory by sniffing the network for data in a handle field.
CVE-2015-2694 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2025-04-12 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-2014-4341 4 Debian, Fedoraproject, Mit and 1 more 11 Debian Linux, Fedora, Kerberos 5 and 8 more 2025-04-12 N/A

CVE-2014-4343 3 Debian, Mit, Redhat 7 Debian Linux, Kerberos 5, Enterprise Linux and 4 more 2025-04-12 N/A
Double free vulnerability in the init_ctx_reselect function in the SPNEGO initiator in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) 1.10.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via network traffic that appears to come from an intended acceptor, but specifies a security mechanism different from the one proposed by the initiator.
CVE-2015-8629 5 Debian, Mit, Opensuse and 2 more 13 Debian Linux, Kerberos 5, Leap and 10 more 2025-04-12 5.3 Medium
The xdr_nullstring function in lib/kadm5/kadm_rpc_xdr.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 does not verify whether '\0' characters exist as expected, which allows remote authenticated users to obtain sensitive information or cause a denial of service (out-of-bounds read) via a crafted string.
CVE-2014-4342 3 Debian, Mit, Redhat 8 Debian Linux, Kerberos, Kerberos 5 and 5 more 2025-04-12 N/A
MIT Kerberos 5 (aka krb5) 1.7.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of service (buffer over-read or NULL pointer dereference, and application crash) by injecting invalid tokens into a GSSAPI application session.
CVE-2015-2695 6 Canonical, Debian, Mit and 3 more 9 Ubuntu Linux, Debian Linux, Kerberos 5 and 6 more 2025-04-12 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-2014-9421 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2025-04-12 N/A
