CVSS v3.1 |
| 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 add_to_history function in svr_principal.c in libkadm5srv for MIT Kerberos 5 (krb5) up to 1.3.5, when performing a password change, does not properly track the password policy's history count and the maximum number of keys, which can cause an array index out-of-bounds error and may allow authenticated users to execute arbitrary code via a heap-based buffer overflow. |
| Certain BSD-based Telnet clients, including those used on Solaris and SuSE Linux, allow remote malicious Telnet servers to read sensitive environment variables via the NEW-ENVIRON option with a SEND ENV_USERVAR command. |
| 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. |
| 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. |
| Double free vulnerability in the krb5_recvauth function in MIT Kerberos 5 (krb5) 1.4.1 and earlier allows remote attackers to execute arbitrary code via certain error conditions. |
| 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. |
| The (1) ftpd and (2) ksu programs in (a) MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, and (b) Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which might allow local users to gain privileges by causing setuid to fail to drop privileges. NOTE: as of 20060808, it is not known whether an exploitable attack scenario exists for these issues. |
| 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"). |
| 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. |
| Kerberos 5 (aka krb5) 1.21.2 contains a memory leak vulnerability in /krb5/src/kdc/ndr.c. |
| 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. |
| telnetd in GNU Inetutils through 2.3, MIT krb5-appl through 1.0.3, and derivative works has a NULL pointer dereference via 0xff 0xf7 or 0xff 0xf8. In a typical installation, the telnetd application would crash but the telnet service would remain available through inetd. However, if the telnetd application has many crashes within a short time interval, the telnet service would become unavailable after inetd logs a "telnet/tcp server failing (looping), service terminated" error. 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. |
| 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. |
| ec_verify in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.4 and 1.19.x before 1.19.2 allows remote attackers to cause a NULL pointer dereference and daemon crash. This occurs because a return value is not properly managed in a certain situation. |
| A flaw was found in, Fedora versions of krb5 from 1.16.1 to, including 1.17.x, in the way a Kerberos client could crash the KDC by sending one of the RFC 4556 "enctypes". A remote unauthenticated user could use this flaw to crash the KDC. |
| 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. |
