CVE-2006-6143 2 Canonical, Mit 2 Ubuntu Linux, Kerberos 5 2025-04-09 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-2006-6144 1 Mit 1 Kerberos 5 2025-04-09 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-2007-3149 2 Mit, Todd Miller 2 Kerberos 5, Sudo 2025-04-09 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-2008-0062 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2025-04-09 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-2007-4000 3 Fedoraproject, Mit, Redhat 3 Fedora, Kerberos 5, Enterprise Linux 2025-04-09 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-2009-0846 5 Apple, Canonical, Fedoraproject and 2 more 9 Mac Os X, Ubuntu Linux, Fedora and 6 more 2025-04-09 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 2025-04-09 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-2007-0956 4 Canonical, Debian, Mit and 1 more 4 Ubuntu Linux, Debian Linux, Kerberos 5 and 1 more 2025-04-09 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-2007-2443 4 Canonical, Debian, Mit and 1 more 4 Ubuntu Linux, Debian Linux, Kerberos 5 and 1 more 2025-04-09 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-2007-3999 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2025-04-09 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-2007-5902 1 Mit 1 Kerberos 5 2025-04-09 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-2008-0063 8 Apple, Canonical, Debian and 5 more 13 Mac Os X, Mac Os X Server, Ubuntu Linux and 10 more 2025-04-09 7.5 High
The Kerberos 4 support in KDC in MIT Kerberos 5 (krb5kdc) does not properly clear the unused portion of a buffer when generating an error message, which might allow remote attackers to obtain sensitive information, aka "Uninitialized stack values."
CVE-2008-0947 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2025-04-09 N/A
Buffer overflow in the RPC library used by libgssrpc and kadmind in MIT Kerberos 5 (krb5) 1.4 through 1.6.3 allows remote attackers to execute arbitrary code by triggering a large number of open file descriptors.
CVE-2000-0549 2 Cygnus, Mit 4 Cygnus Network Security, Kerbnet, Kerberos and 1 more 2025-04-03 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-1999-0143 3 Mit, Process Software, Sun 4 Kerberos, Kerberos 5, Multinet and 1 more 2025-04-03 N/A
Kerberos 4 key servers allow a user to masquerade as another by breaking and generating session keys.
CVE-2001-0417 1 Mit 2 Kerberos, Kerberos 5 2025-04-03 N/A
Kerberos 4 (aka krb4) allows local users to overwrite arbitrary files via a symlink attack on new ticket files.
CVE-2001-0247 5 Freebsd, Mit, Netbsd and 2 more 5 Freebsd, Kerberos 5, Netbsd and 2 more 2025-04-03 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-2000-0550 2 Cygnus, Mit 4 Cygnus Network Security, Kerbnet, Kerberos and 1 more 2025-04-03 N/A
Kerberos 4 KDC program improperly frees memory twice (aka "double-free"), which allows remote attackers to cause a denial of service.
CVE-2006-3083 3 Heimdal, Mit, Redhat 3 Heimdal, Kerberos 5, Enterprise Linux 2025-04-03 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.
