| 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-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-2005-0488 | 4 Microsoft, Mit, Redhat and 1 more | 4 Telnet Client, Kerberos 5, Enterprise Linux and 1 more | 2026-04-16 | N/A |
| Certain BSD-based Telnet clients, including those used on Solaris and SuSE Linux, allow remote malicious Telnet servers to read sensitive environment variables via the NEW-ENVIRON option with a SEND ENV_USERVAR command. | ||||
| CVE-2006-3084 | 2 Heimdal, Mit | 2 Heimdal, Kerberos 5 | 2026-04-16 | N/A |
| The (1) ftpd and (2) ksu programs in (a) MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, and (b) Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which might allow local users to gain privileges by causing setuid to fail to drop privileges. NOTE: as of 20060808, it is not known whether an exploitable attack scenario exists for these issues. | ||||
| CVE-2001-0554 | 10 Debian, Freebsd, Ibm and 7 more | 12 Debian Linux, Freebsd, Aix and 9 more | 2026-04-16 | 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-2020-28196 | 5 Fedoraproject, Mit, Netapp and 2 more | 13 Fedora, Kerberos 5, Active Iq Unified Manager and 10 more | 2025-12-03 | 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-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-2011-0285 | 2 Mit, Redhat | 2 Kerberos 5, Enterprise Linux | 2025-04-11 | N/A |
| The process_chpw_request function in schpw.c in the password-changing functionality in kadmind in MIT Kerberos 5 (aka krb5) 1.7 through 1.9 frees an invalid pointer, which allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a crafted request that triggers an error condition. | ||||
| CVE-2002-2443 | 6 Canonical, Debian, Fedoraproject and 3 more | 11 Ubuntu Linux, Debian Linux, Fedora and 8 more | 2025-04-11 | N/A |
| schpw.c in the kpasswd service in kadmind in MIT Kerberos 5 (aka krb5) before 1.11.3 does not properly validate UDP packets before sending responses, which allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged packet that triggers a communication loop, as demonstrated by krb_pingpong.nasl, a related issue to CVE-1999-0103. | ||||
| CVE-2022-39028 | 4 Debian, Gnu, Mit and 1 more | 4 Debian Linux, Inetutils, Kerberos 5 and 1 more | 2024-11-21 | 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. | ||||
