CVE-2022-42898 3 Heimdal Project, Mit, Samba 3 Heimdal, Kerberos 5, Samba 2023-02-23 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-2019-14844 2 Fedoraproject, Mit 2 Fedora, Kerberos 5 2023-02-12 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 2023-02-12 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.
CVE-2022-39028 3 Debian, Gnu, Mit 3 Debian Linux, Inetutils, Kerberos 5 2022-11-29 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 2022-10-25 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-1999-0143 3 Mit, Process Software, Sun 4 Kerberos, Kerberos 5, Multinet and 1 more 2022-08-17 4.6 MEDIUM N/A
Kerberos 4 key servers allow a user to masquerade as another by breaking and generating session keys.
CVE-2020-28196 4 Fedoraproject, Mit, Netapp and 1 more 11 Fedora, Kerberos 5, Active Iq Unified Manager and 8 more 2022-05-12 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-2018-5730 4 Debian, Fedoraproject, Mit and 1 more 6 Debian Linux, Fedora, Kerberos 5 and 3 more 2022-04-18 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-2001-0554 9 Debian, Freebsd, Ibm and 6 more 11 Debian Linux, Freebsd, Aix and 8 more 2022-01-21 10.0 HIGH N/A
Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function.
CVE-2021-36222 4 Debian, Mit, Netapp and 1 more 7 Debian Linux, Kerberos 5, Active Iq Unified Manager and 4 more 2021-11-28 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-2001-1323 1 Mit 1 Kerberos 5 2021-11-04 7.5 HIGH N/A
Buffer overflow in MIT Kerberos 5 (krb5) 1.2.2 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via base-64 encoded data, which is not properly handled when the radix_encode function processes file glob output from the ftpglob function.
CVE-2018-5729 4 Debian, Fedoraproject, Mit and 1 more 6 Debian Linux, Fedora, Kerberos 5 and 3 more 2021-10-18 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-2004-0971 1 Mit 1 Kerberos 5 2021-06-18 2.1 LOW N/A
The krb5-send-pr script in the kerberos5 (krb5) package in Trustix Secure Linux 1.5 through 2.1, and possibly other operating systems, allows local users to overwrite files via a symlink attack on temporary files.
CVE-2015-8629 5 Debian, Mit, Opensuse and 2 more 12 Debian Linux, Kerberos 5, Leap and 9 more 2021-02-02 2.1 LOW 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-2015-8631 5 Debian, Mit, Opensuse and 2 more 11 Debian Linux, Kerberos 5, Leap and 8 more 2021-02-02 4.0 MEDIUM 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 2021-02-02 4.0 MEDIUM 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-2015-2695 6 Canonical, Debian, Mit and 3 more 9 Ubuntu Linux, Debian Linux, Kerberos 5 and 6 more 2021-02-02 5.0 MEDIUM 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-2013-1418 3 Debian, Mit, Opensuse 3 Debian Linux, Kerberos 5, Opensuse 2021-02-02 4.3 MEDIUM N/A
The setup_server_realm function in main.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.7, when multiple realms are configured, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request.
CVE-2014-4341 4 Debian, Fedoraproject, Mit and 1 more 10 Debian Linux, Fedora, Kerberos 5 and 7 more 2021-02-02 5.0 MEDIUM N/A
MIT Kerberos 5 (aka krb5) before 1.12.2 allows remote attackers to cause a denial of service (buffer over-read and application crash) by injecting invalid tokens into a GSSAPI application session.
CVE-2014-5353 7 Canonical, Debian, Fedoraproject and 4 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2021-02-02 3.5 LOW 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.
