|---|---|---|---|---|---|
| CVE-2017-6594 | 2 Heimdal Project, Opensuse | 2 Heimdal, Leap | 2021-08-12 | 5.0 MEDIUM | 7.5 HIGH |
| The transit path validation code in Heimdal before 7.3 might allow attackers to bypass the capath policy protection mechanism by leveraging failure to add the previous hop realm to the transit path of issued tickets. | |||||
| CVE-2019-12098 | 1 Heimdal Project | 1 Heimdal | 2021-07-21 | 5.8 MEDIUM | 7.4 HIGH |
| In the client side of Heimdal before 7.6.0, failure to verify anonymous PKINIT PA-PKINIT-KX key exchange permits a man-in-the-middle attack. This issue is in krb5_init_creds_step in lib/krb5/init_creds_pw.c. | |||||
| CVE-2011-4862 | 8 Debian, Fedoraproject, Freebsd and 5 more | 10 Debian Linux, Fedora, Freebsd and 7 more | 2021-02-09 | 10.0 HIGH | N/A |
| Buffer overflow in libtelnet/encrypt.c in telnetd in FreeBSD 7.3 through 9.0, MIT Kerberos Version 5 Applications (aka krb5-appl) 1.0.2 and earlier, Heimdal 1.5.1 and earlier, GNU inetutils, and possibly other products allows remote attackers to execute arbitrary code via a long encryption key, as exploited in the wild in December 2011. | |||||
| CVE-2004-0434 | 2 Debian, Heimdal Project | 2 Debian Linux, Heimdal | 2020-11-16 | 10.0 HIGH | N/A |
| k5admind (kadmind) for Heimdal allows remote attackers to execute arbitrary code via a Kerberos 4 compatibility administration request whose framing length is less than 2, which leads to a heap-based buffer overflow. | |||||
| CVE-2017-11103 | 5 Apple, Debian, Freebsd and 2 more | 6 Iphone Os, Mac Os X, Debian Linux and 3 more | 2020-08-18 | 6.8 MEDIUM | 8.1 HIGH |
| Heimdal before 7.4 allows remote attackers to impersonate services with Orpheus' Lyre attacks because it obtains service-principal names in a way that violates the Kerberos 5 protocol specification. In _krb5_extract_ticket() the KDC-REP service name must be obtained from the encrypted version stored in 'enc_part' instead of the unencrypted version stored in 'ticket'. Use of the unencrypted version provides an opportunity for successful server impersonation and other attacks. NOTE: this CVE is only for Heimdal and other products that embed Heimdal code; it does not apply to other instances in which this part of the Kerberos 5 protocol specification is violated. | |||||
| CVE-2018-16860 | 2 Heimdal Project, Samba | 2 Heimdal, Samba | 2019-08-14 | 6.0 MEDIUM | 7.5 HIGH |
| A flaw was found in samba's Heimdal KDC implementation, versions 4.8.x up to, excluding 4.8.12, 4.9.x up to, excluding 4.9.8 and 4.10.x up to, excluding 4.10.3, when used in AD DC mode. A man in the middle attacker could use this flaw to intercept the request to the KDC and replace the user name (principal) in the request with any desired user name (principal) that exists in the KDC effectively obtaining a ticket for that principal. | |||||
| CVE-2017-17439 | 2 Debian, Heimdal Project | 2 Debian Linux, Heimdal | 2017-12-30 | 5.0 MEDIUM | 7.5 HIGH |
| In Heimdal through 7.4, remote unauthenticated attackers are able to crash the KDC by sending a crafted UDP packet containing empty data fields for client name or realm. The parser would unconditionally dereference NULL pointers in that case, leading to a segmentation fault. This is related to the _kdc_as_rep function in kdc/kerberos5.c and the der_length_visible_string function in lib/asn1/der_length.c. | |||||
