EPSS score
2.62%
The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.9 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a malformed request packet that does not trigger a response packet.
5CVE-2011-0281debiankrb5+2
EPSS score
4.20%
The unparse implementation in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.6.x through 1.9, when an LDAP backend is used, allows remote attackers to cause a denial of service (file descriptor exhaustion and daemon hang) via a principal name that triggers use of a backslash escape sequence, as demonstrated by a \n sequence.
10CVE-2011-0285debiankrb5+9
EPSS score
20.77%
The process_chpw_request function in schpw.c in the password-changing functionality in kadmind in MIT Kerberos 5 (aka krb5) 1.7 through 1.9 frees an invalid pointer, which allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a crafted request that triggers an error condition.
7.6CVE-2011-0284debiankrb5+9
EPSS score
8.27%
Double free vulnerability in the prepare_error_as function in do_as_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.7 through 1.9, when the PKINIT feature is enabled, allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via an e_data field containing typed data.
5CVE-2011-0282debiankrb5+2
EPSS score
3.48%
The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.6.x through 1.9, when an LDAP backend is used, allows remote attackers to cause a denial of service (NULL pointer dereference or buffer over-read, and daemon crash) via a crafted principal name.
7.8CVE-2011-4151debiankrb5+1
EPSS score
3.54%
The krb5_db2_lockout_audit function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8 through 1.8.4, when the db2 (aka Berkeley DB) back end is used, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via unspecified vectors, a different vulnerability than CVE-2011-1528.
3.7CVE-2010-1323debiankrb5+8
EPSS score
2.85%
MIT Kerberos 5 (aka krb5) 1.3.x, 1.4.x, 1.5.x, 1.6.x, 1.7.x, and 1.8.x through 1.8.3 does not properly determine the acceptability of checksums, which might allow remote attackers to modify user-visible prompt text, modify a response to a Key Distribution Center (KDC), or forge a KRB-SAFE message via certain checksums that (1) are unkeyed or (2) use RC4 keys.
6.8CVE-2010-1321canonicalubuntu_linux+14
EPSS score
6.88%
The kg_accept_krb5 function in krb5/accept_sec_context.c in the GSS-API library in MIT Kerberos 5 (aka krb5) through 1.7.1 and 1.8 before 1.8.2, as used in kadmind and other applications, does not properly check for invalid GSS-API tokens, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an AP-REQ message in which the authenticator's checksum field is missing.
4.3CVE-2010-1324debiankrb5+1
EPSS score
2.25%
MIT Kerberos 5 (aka krb5) 1.7.x and 1.8.x through 1.8.3 does not properly determine the acceptability of checksums, which might allow remote attackers to forge GSS tokens, gain privileges, or have unspecified other impact via (1) an unkeyed checksum, (2) an unkeyed PAC checksum, or (3) a KrbFastArmoredReq checksum based on an RC4 key.
4CVE-2010-1320debiankrb5+1
EPSS score
11.86%
Double free vulnerability in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.7.x and 1.8.x before 1.8.2 allows remote authenticated users to cause a denial of service (daemon crash) or possibly execute arbitrary code via a request associated with (1) renewal or (2) validation.

EPSS score
3.04%
The merge_authdata function in kdc_authdata.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8.x before 1.8.4 does not properly manage an index into an authorization-data list, which allows remote attackers to cause a denial of service (daemon crash), or possibly obtain sensitive information, spoof authorization, or execute arbitrary code, via a TGS request that triggers an uninitialized pointer dereference, as demonstrated by a request from a Windows Active Directory client.
7.8CVE-2010-0283debiankrb5+2
EPSS score
2.41%
The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.7 before 1.7.2, and 1.8 alpha, allows remote attackers to cause a denial of service (assertion failure and daemon crash) via an invalid (1) AS-REQ or (2) TGS-REQ request.

EPSS score
5.47%
Use-after-free vulnerability in kadmin/server/server_stubs.c in kadmind in MIT Kerberos 5 (aka krb5) 1.5 through 1.6.3 allows remote authenticated users to cause a denial of service (daemon crash) via a request from a kadmin client that sends an invalid API version number.
