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-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-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-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-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-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-2007-5972 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-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-2009-0847 1 Mit 1 Kerberos 2026-04-23 N/A
The asn1buf_imbed function in the ASN.1 decoder in MIT Kerberos 5 (aka krb5) 1.6.3, when PK-INIT is used, allows remote attackers to cause a denial of service (application crash) via a crafted length value that triggers an erroneous malloc call, related to incorrect calculations with pointer arithmetic.
CVE-2007-2443 4 Canonical, Debian, Mit and 1 more 4 Ubuntu Linux, Debian Linux, Kerberos 5 and 1 more 2026-04-23 N/A
Integer signedness error in the gssrpc__svcauth_unix function in svc_auth_unix.c in the RPC library in MIT Kerberos 5 (krb5) 1.6.1 and earlier might allow remote attackers to execute arbitrary code via a negative length value.
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-2002-1575 1 Mit 1 Cgiemail 2026-04-16 N/A
cgiemail allows remote attackers to use cgiemail as a spam proxy via CRLF injection of encoded newline (%0a) characters in parameters such as "required-subject," which can be used to modify the CC, BCC, and other header fields in the generated email message.
CVE-2004-0523 5 Mit, Redhat, Sgi and 2 more 8 Kerberos, Kerberos 5, Enterprise Linux and 5 more 2026-04-16 N/A
Multiple buffer overflows in krb5_aname_to_localname for MIT Kerberos 5 (krb5) 1.3.3 and earlier allow remote attackers to execute arbitrary code as root.
CVE-2000-0549 2 Cygnus, Mit 4 Cygnus Network Security, Kerbnet, Kerberos and 1 more 2026-04-16 N/A
Kerberos 4 KDC program does not properly check for null termination of AUTH_MSG_KDC_REQUEST requests, which allows remote attackers to cause a denial of service via a malformed request.
CVE-2004-0971 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-04-16 N/A
The krb5-send-pr script in the kerberos5 (krb5) package in Trustix Secure Linux 1.5 through 2.1, and possibly other operating systems, allows local users to overwrite files via a symlink attack on temporary files.

Buffer overflow in Kerberos 4 KDC program allows remote attackers to cause a denial of service via the localrealm variable in the process_v4 function.
CVE-2001-0247 5 Freebsd, Mit, Netbsd and 2 more 5 Freebsd, Kerberos 5, Netbsd and 2 more 2026-04-16 N/A
Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) g_opendir, (2) g_lstat, (3) g_stat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3.
CVE-2000-0392 3 Cygnus, Mit, Redhat 5 Cygnus Network Security, Kerbnet, Kerberos and 2 more 2026-04-16 N/A
