CVE-2023-36054 3 Debian, Mit, Netapp 7 Debian Linux, Kerberos 5, Active Iq Unified Manager and 4 more 2023-11-15 N/A 6.5 MEDIUM
lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) before 1.20.2 and 1.21.x before 1.21.1 frees an uninitialized pointer. A remote authenticated user can trigger a kadmind crash. This occurs because _xdr_kadm5_principal_ent_rec does not validate the relationship between n_key_data and the key_data array count.
CVE-2021-37750 3 Debian, Fedoraproject, Mit 3 Debian Linux, Fedora, Kerberos 5 2022-07-25 4.0 MEDIUM 6.5 MEDIUM
The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.5 and 1.19.x before 1.19.3 has a NULL pointer dereference in kdc/do_tgs_req.c via a FAST inner body that lacks a server field.
CVE-2020-27428 1 Mit 1 Scratch-svg-renderer 2022-01-12 4.3 MEDIUM 6.1 MEDIUM
A DOM-based cross-site scripting (XSS) vulnerability in Scratch-Svg-Renderer v0.2.0 allows attackers to execute arbitrary web scripts or HTML via a crafted sb3 file.
CVE-2018-5729 4 Debian, Fedoraproject, Mit and 1 more 6 Debian Linux, Fedora, Kerberos 5 and 3 more 2021-10-18 6.5 MEDIUM 4.7 MEDIUM
MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to cause a denial of service (NULL pointer dereference) or bypass a DN container check by supplying tagged data that is internal to the database module.
CVE-2018-20217 2 Debian, Mit 2 Debian Linux, Kerberos 2021-10-18 3.5 LOW 5.3 MEDIUM
A Reachable Assertion issue was discovered in the KDC in MIT Kerberos 5 (aka krb5) before 1.17. If an attacker can obtain a krbtgt ticket using an older encryption type (single-DES, triple-DES, or RC4), the attacker can crash the KDC by making an S4U2Self request.
CVE-2019-25017 1 Mit 1 Krb5-appl 2021-07-21 5.8 MEDIUM 5.9 MEDIUM
An issue was discovered in rcp in MIT krb5-appl through 1.0.3. Due to the rcp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the rcp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious rcp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rcp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file). This issue is similar to CVE-2019-6111 and CVE-2019-7283. NOTE: MIT krb5-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8.
CVE-2015-8629 5 Debian, Mit, Opensuse and 2 more 12 Debian Linux, Kerberos 5, Leap and 9 more 2021-02-02 2.1 LOW 5.3 MEDIUM
The xdr_nullstring function in lib/kadm5/kadm_rpc_xdr.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 does not verify whether '\0' characters exist as expected, which allows remote authenticated users to obtain sensitive information or cause a denial of service (out-of-bounds read) via a crafted string.
CVE-2015-8631 5 Debian, Mit, Opensuse and 2 more 11 Debian Linux, Kerberos 5, Leap and 8 more 2021-02-02 4.0 MEDIUM 6.5 MEDIUM
Multiple memory leaks in kadmin/server/server_stubs.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 allow remote authenticated users to cause a denial of service (memory consumption) via a request specifying a NULL principal name.
CVE-2017-7562 2 Mit, Redhat 5 Kerberos 5, Enterprise Linux, Enterprise Linux Desktop and 2 more 2020-01-21 4.0 MEDIUM 6.5 MEDIUM
An authentication bypass flaw was found in the way krb5's certauth interface before 1.16.1 handled the validation of client certificates. A remote attacker able to communicate with the KDC could potentially use this flaw to impersonate arbitrary principals under rare and erroneous circumstances.
CVE-2016-3119 2 Mit, Opensuse 3 Kerberos 5, Leap, Opensuse 2020-01-21 3.5 LOW 5.3 MEDIUM
The process_db_args function in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the LDAP KDB module in kadmind in MIT Kerberos 5 (aka krb5) through 1.13.4 and 1.14.x through 1.14.1 mishandles the DB argument, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request to modify a principal.
CVE-2016-3120 1 Mit 1 Kerberos 5 2020-01-21 4.0 MEDIUM 6.5 MEDIUM
The validate_as_request function in kdc_util.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.13.6 and 1.4.x before 1.14.3, when restrict_anonymous_to_tgt is enabled, uses an incorrect client data structure, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an S4U2Self request.
CVE-2017-11368 2 Fedoraproject, Mit 3 Fedora, Kerberos, Kerberos 5 2020-01-21 4.0 MEDIUM 6.5 MEDIUM
In MIT Kerberos 5 (aka krb5) 1.7 and later, an authenticated attacker can cause a KDC assertion failure by sending invalid S4U2Self or S4U2Proxy requests.
CVE-2010-4020 1 Mit 1 Kerberos 5 2020-01-21 3.5 LOW 6.3 MEDIUM
MIT Kerberos 5 (aka krb5) 1.8.x through 1.8.3 does not reject RC4 key-derivation checksums, which might allow remote authenticated users to forge a (1) AD-SIGNEDPATH or (2) AD-KDC-ISSUED signature, and possibly gain privileges, by leveraging the small key space that results from certain one-byte stream-cipher operations.
CVE-2018-5710 1 Mit 1 Kerberos 2018-08-13 4.0 MEDIUM 6.5 MEDIUM
An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. The pre-defined function "strlen" is getting a "NULL" string as a parameter value in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the Key Distribution Center (KDC), which allows remote authenticated users to cause a denial of service (NULL pointer dereference) via a modified kadmin client.
