The add_to_history function in svr_principal.c in libkadm5srv for MIT Kerberos 5 (krb5) up to 1.3.5, when performing a password change, does not properly track the password policy's history count and the maximum number of keys, which can cause an array index out-of-bounds error and may allow authenticated users to execute arbitrary code via a heap-based buffer overflow.
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-2005-1174 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-04-16 N/A
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-2006-3083 3 Heimdal, Mit, Redhat 3 Heimdal, Kerberos 5, Enterprise Linux 2026-04-16 N/A
The (1) krshd and (2) v4rcp applications in (a) MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, when running on Linux and AIX, and (b) Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which allows local users to gain privileges by causing setuid to fail to drop privileges using attacks such as resource exhaustion.
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-2003-0139 2 Mit, Redhat 3 Kerberos, Enterprise Linux, Linux 2026-04-16 N/A
Certain weaknesses in the implementation of version 4 of the Kerberos protocol (krb4) in the krb5 distribution, when triple-DES keys are used to key krb4 services, allow an attacker to create krb4 tickets for unauthorized principals using a cut-and-paste attack and "ticket splicing."
CVE-2000-0392 3 Cygnus, Mit, Redhat 5 Cygnus Network Security, Kerbnet, Kerberos and 2 more 2026-04-16 N/A
Buffer overflow in ksu in Kerberos 5 allows local users to gain root privileges.
CVE-2000-0390 3 Cygnus, Mit, Redhat 5 Cygnus Network Security, Kerbnet, Kerberos and 2 more 2026-04-16 N/A
Buffer overflow in krb425_conv_principal function in Kerberos 5 allows remote attackers to gain root privileges.

Buffer overflow in krb_rd_req function in Kerberos 4 and 5 allows remote attackers to gain root privileges.
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-1999-1296 1 Mit 1 Kerberos 5 2026-04-16 N/A
Buffer overflow in Kerberos IV compatibility libraries as used in Kerberos V allows local users to gain root privileges via a long line in a kerberos configuration file, which can be specified via the KRB_CONF environmental variable.

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-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.
