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-2007-4743 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-2007-5894 1 Mit 1 Kerberos 5 2026-04-23 N/A
The reply function in ftpd.c in the gssftp ftpd in MIT Kerberos 5 (krb5) does not initialize the length variable when auth_type has a certain value, which has unknown impact and remote authenticated attack vectors. NOTE: the original disclosure misidentifies the conditions under which the uninitialized variable is used. NOTE: the vendor disputes this issue, stating " The 'length' variable is only uninitialized if 'auth_type' is neither the 'KERBEROS_V4' nor 'GSSAPI'; this condition cannot occur in the unmodified source code.
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-2007-1216 4 Canonical, Debian, Mit and 1 more 4 Ubuntu Linux, Debian Linux, Kerberos 5 and 1 more 2026-04-23 N/A
Double free vulnerability in the GSS-API library (lib/gssapi/krb5/k5unseal.c), as used by the Kerberos administration daemon (kadmind) in MIT krb5 before 1.6.1, when used with the authentication method provided by the RPCSEC_GSS RPC library, allows remote authenticated users to execute arbitrary code and modify the Kerberos key database via a message with an "an invalid direction encoding".
CVE-2009-0846 5 Apple, Canonical, Fedoraproject and 2 more 9 Mac Os X, Ubuntu Linux, Fedora and 6 more 2026-04-23 N/A
The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 (aka krb5) before 1.6.4 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer.
CVE-2007-2798 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 rename_principal_2_svc function in kadmind for MIT Kerberos 1.5.3, 1.6.1, and other versions allows remote authenticated users to execute arbitrary code via a crafted request to rename a principal.
CVE-2009-0845 2 Mit, Redhat 3 Kerberos, Kerberos 5, Enterprise Linux 2026-04-23 N/A
The spnego_gss_accept_sec_context function in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) 1.5 through 1.6.3, when SPNEGO is used, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via invalid ContextFlags data in the reqFlags field in a negTokenInit token.
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-2000-0391 3 Cygnus, Mit, Redhat 5 Cygnus Network Security, Kerbnet, Kerberos and 2 more 2026-04-16 N/A
Buffer overflow in krshd in Kerberos 5 allows remote attackers to gain root privileges.

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-2003-0082 2 Mit, Redhat 4 Kerberos, Kerberos 5, Enterprise Linux and 1 more 2026-04-16 N/A
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 the KDC to corrupt its heap (aka "buffer underrun").
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.
