CVE-2007-4000 3 Fedoraproject, Mit, Redhat 3 Fedora, Kerberos 5, Enterprise Linux 2026-04-23 N/A
The kadm5_modify_policy_internal function in lib/kadm5/srv/svr_policy.c in the Kerberos administration daemon (kadmind) in MIT Kerberos 5 (krb5) 1.5 through 1.6.2 does not properly check return values when the policy does not exist, which might allow remote authenticated users with the "modify policy" privilege to execute arbitrary code via unspecified vectors that trigger a write to an uninitialized pointer.
CVE-2007-4743 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-04-23 N/A
The original patch for CVE-2007-3999 in svc_auth_gss.c in the RPCSEC_GSS RPC library in MIT Kerberos 5 (krb5) 1.4 through 1.6.2, as used by the Kerberos administration daemon (kadmind) and other applications that use krb5, does not correctly check the buffer length in some environments and architectures, which might allow remote attackers to conduct a buffer overflow attack.
CVE-2009-0844 2 Mit, Redhat 3 Kerberos, Kerberos 5, Enterprise Linux 2026-04-23 N/A
The get_input_token function in the SPNEGO implementation in MIT Kerberos 5 (aka krb5) 1.5 through 1.6.3 allows remote attackers to cause a denial of service (daemon crash) and possibly obtain sensitive information via a crafted length value that triggers a buffer over-read.
CVE-2008-0062 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-04-23 9.8 Critical
KDC in MIT Kerberos 5 (krb5kdc) does not set a global variable for some krb4 message types, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted messages that trigger a NULL pointer dereference or double-free.
CVE-2007-3999 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-04-23 N/A
Stack-based buffer overflow in the svcauth_gss_validate function in lib/rpc/svc_auth_gss.c in the RPCSEC_GSS RPC library (librpcsecgss) in MIT Kerberos 5 (krb5) 1.4 through 1.6.2, as used by the Kerberos administration daemon (kadmind) and some third-party applications that use krb5, allows remote attackers to cause a denial of service (daemon crash) and probably execute arbitrary code via a long string in an RPC message.
CVE-2007-3149 2 Mit, Todd Miller 2 Kerberos 5, Sudo 2026-04-23 N/A
sudo, when linked with MIT Kerberos 5 (krb5), does not properly check whether a user can currently authenticate to Kerberos, which allows local users to gain privileges, in a manner unintended by the sudo security model, via certain KRB5_ environment variable settings. NOTE: another researcher disputes this vulnerability, stating that the attacker must be "a user, who can already log into your system, and can already use sudo."
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-2007-5902 1 Mit 1 Kerberos 5 2026-04-23 N/A
Integer overflow in the svcauth_gss_get_principal function in lib/rpc/svc_auth_gss.c in MIT Kerberos 5 (krb5) allows remote attackers to have an unknown impact via a large length value for a GSS client name in an RPC request.
CVE-2007-5972 1 Mit 1 Kerberos 5 2026-04-23 N/A
Double free vulnerability in the krb5_def_store_mkey function in lib/kdb/kdb_default.c in MIT Kerberos 5 (krb5) 1.5 has unknown impact and remote authenticated attack vectors. NOTE: the free operations occur in code that stores the krb5kdc master key, and so the attacker must have privileges to store this key.
CVE-2007-0956 4 Canonical, Debian, Mit and 1 more 4 Ubuntu Linux, Debian Linux, Kerberos 5 and 1 more 2026-04-23 N/A
The telnet daemon (telnetd) in MIT krb5 before 1.6.1 allows remote attackers to bypass authentication and gain system access via a username beginning with a '-' character, a similar issue to CVE-2007-0882.
CVE-2007-0957 4 Canonical, Debian, Mit and 1 more 4 Ubuntu Linux, Debian Linux, Kerberos 5 and 1 more 2026-04-23 N/A
Stack-based buffer overflow in the krb5_klog_syslog function in the kadm5 library, as used by the Kerberos administration daemon (kadmind) and Key Distribution Center (KDC), in MIT krb5 before 1.6.1 allows remote authenticated users to execute arbitrary code and modify the Kerberos key database via crafted arguments, possibly involving certain format string specifiers.
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-2002-1235 4 Debian, Kth, Mit and 1 more 6 Debian Linux, Kth Kerberos 4, Kth Kerberos 5 and 3 more 2026-04-16 N/A
The kadm_ser_in function in (1) the Kerberos v4compatibility administration daemon (kadmind4) in the MIT Kerberos 5 (krb5) krb5-1.2.6 and earlier, (2) kadmind in KTH Kerberos 4 (eBones) before 1.2.1, and (3) kadmind in KTH Kerberos 5 (Heimdal) before 0.5.1 when compiled with Kerberos 4 support, does not properly verify the length field of a request, which allows remote attackers to execute arbitrary code via a buffer overflow attack.
CVE-2005-1689 4 Apple, Debian, Mit and 1 more 5 Mac Os X, Mac Os X Server, Debian Linux and 2 more 2026-04-16 9.8 Critical
Double free vulnerability in the krb5_recvauth function in MIT Kerberos 5 (krb5) 1.4.1 and earlier allows remote attackers to execute arbitrary code via certain error conditions.
CVE-2003-0059 2 Mit, Redhat 3 Kerberos 5, Enterprise Linux, Linux 2026-04-16 N/A
Unknown vulnerability in the chk_trans.c of the libkrb5 library for MIT Kerberos V5 before 1.2.5 allows users from one realm to impersonate users in other realms that have the same inter-realm keys.
CVE-2000-0514 1 Mit 1 Kerberos 5 2026-04-16 N/A
GSSFTP FTP daemon in Kerberos 5 1.1.x does not properly restrict access to some FTP commands, which allows remote attackers to cause a denial of service, and local users to gain root privileges.
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-2002-0036 2 Mit, Redhat 3 Kerberos 5, Enterprise Linux, Linux 2026-04-16 N/A
Integer signedness error in MIT Kerberos V5 ASN.1 decoder before krb5 1.2.5 allows remote attackers to cause a denial of service via a large unsigned data element length, which is later used as a negative value.
CVE-2003-0060 1 Mit 1 Kerberos 5 2026-04-16 N/A
Format string vulnerabilities in the logging routines for MIT Kerberos V5 Key Distribution Center (KDC) before 1.2.5 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via format string specifiers in Kerberos principal names.
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.
