MIT Kerberos 5 (krb5) 1.3 through 1.4.1 Key Distribution Center (KDC) allows remote attackers to cause a denial of service (application crash) via a certain valid TCP connection that causes a free of unallocated memory.
CVE-2004-0772 4 Debian, Mit, Openpkg and 1 more 4 Debian Linux, Kerberos 5, Openpkg and 1 more 2026-04-16 9.8 Critical
Double free vulnerabilities in error handling code in krb524d for MIT Kerberos 5 (krb5) 1.2.8 and earlier may allow remote attackers to execute arbitrary code.
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-2004-0643 3 Debian, Mit, Redhat 6 Debian Linux, Kerberos 5, Enterprise Linux and 3 more 2026-04-16 N/A
Double free vulnerability in the krb5_rd_cred function for MIT Kerberos 5 (krb5) 1.3.1 and earlier may allow local users to execute arbitrary code.

The Key Distribution Center (KDC) in Kerberos 5 (krb5) 1.2.7 and earlier allows remote, authenticated attackers to cause a denial of service (crash) on KDCs within the same realm using a certain protocol request that causes an out-of-bounds read of an array (aka "array overrun").
CVE-2003-0138 2 Mit, Redhat 3 Kerberos, Enterprise Linux, Linux 2026-04-16 N/A
Version 4 of the Kerberos protocol (krb4), as used in Heimdal and other packages, allows an attacker to impersonate any principal in a realm via a chosen-plaintext attack.
CVE-2000-0550 2 Cygnus, Mit 4 Cygnus Network Security, Kerbnet, Kerberos and 1 more 2026-04-16 N/A
Kerberos 4 KDC program improperly frees memory twice (aka "double-free"), which allows remote attackers to cause a denial of service.
CVE-2005-1175 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-04-16 N/A
Heap-based buffer overflow in the Key Distribution Center (KDC) in MIT Kerberos 5 (krb5) 1.4.1 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a certain valid TCP or UDP request.
CVE-2003-0028 11 Cray, Freebsd, Gnu and 8 more 15 Unicos, Freebsd, Glibc and 12 more 2026-04-16 N/A
Integer overflow in the xdrmem_getbytes() function, and possibly other functions, of XDR (external data representation) libraries derived from SunRPC, including libnsl, libc, glibc, and dietlibc, allows remote attackers to execute arbitrary code via certain integer values in length fields, a different vulnerability than CVE-2002-0391.
CVE-2004-0642 3 Debian, Mit, Redhat 6 Debian Linux, Kerberos 5, Enterprise Linux and 3 more 2026-04-16 N/A
Double free vulnerabilities in the error handling code for ASN.1 decoders in the (1) Key Distribution Center (KDC) library and (2) client library for MIT Kerberos 5 (krb5) 1.3.4 and earlier may allow remote attackers to execute arbitrary code.
CVE-2025-24528 2 Mit, Redhat 5 Kerberos 5, Discovery, Enterprise Linux and 2 more 2026-04-15 7.1 High
In MIT Kerberos 5 (aka krb5) before 1.22 (with incremental propagation), there is an integer overflow for a large update size to resize() in kdb_log.c. An authenticated attacker can cause an out-of-bounds write and kadmind daemon crash.
CVE-2023-39975 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-02-25 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-2024-37370 2 Mit, Redhat 8 Kerberos 5, Enterprise Linux, Rhel Aus and 5 more 2026-02-18 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-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-2024-37371 3 Debian, Mit, Redhat 9 Debian Linux, Kerberos 5, Enterprise Linux and 6 more 2025-11-03 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.

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-2018-5730 4 Debian, Fedoraproject, Mit and 1 more 7 Debian Linux, Fedora, Kerberos 5 and 4 more 2025-05-05 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.
