CVSS v3.1 |
| 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". |
| The gssrpc__svcauth_gssapi function in the RPC library in MIT Kerberos 5 (krb5) 1.6.1 and earlier might allow remote attackers to execute arbitrary code via a zero-length RPC credential, which causes kadmind to free an uninitialized pointer during cleanup. |
| 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." |
| The prep_reprocess_req function in kdc/do_tgs_req.c in the cross-realm referral implementation in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.7 before 1.7.1 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a ticket request. |
| 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. |
| 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. |
| Multiple integer underflows in the (1) AES and (2) RC4 decryption functionality in the crypto library in MIT Kerberos 5 (aka krb5) 1.3 through 1.6.3, and 1.7 before 1.7.1, allow remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code by providing ciphertext with a length that is too short to be valid. |
| Buffer overflow in the RPC library (lib/rpc/rpc_dtablesize.c) used by libgssrpc and kadmind in MIT Kerberos 5 (krb5) 1.2.2, and probably other versions before 1.3, when running on systems whose unistd.h does not define the FD_SETSIZE macro, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by triggering a large number of open file descriptors. |
| 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. |
| 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. |
| The asn1buf_skiptail function in the ASN.1 decoder library for MIT Kerberos 5 (krb5) 1.2.2 through 1.3.4 allows remote attackers to cause a denial of service (infinite loop) via a certain BER encoding. |
| 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. |
| Kerberos 4 (aka krb4) allows local users to overwrite arbitrary files via a symlink attack on new ticket files. |
| 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. |
| 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"). |
| 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. |
| Buffer overflow in krb_rd_req function in Kerberos 4 and 5 allows remote attackers to gain root privileges. |
| 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. |
| 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. |
| Buffer overflow in ksu in Kerberos 5 allows local users to gain root privileges. |
