| CVE-2004-0434 | Cri | 0.64 | 9.8 | 0.07 | Jul 7, 2004 | 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 | Hig | 0.53 | 8.1 | 0.05 | Jul 13, 2017 | 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… | ||
| CVE-2018-5349 | Hig | 0.51 | 7.8 | 0.00 | Mar 22, 2018 | A vulnerability has been found in Heimdal PRO v2.2.190, but it is most likely also present in Heimdal FREE and Heimdal CORP. Faulty permissions on the directory "C:\ProgramData\Heimdal Security\Heimdal Agent" allow BUILTIN\Users to write new files to the directory. On startup,… | ||
| CVE-2017-17439 | Hig | 0.49 | 7.5 | 0.03 | Dec 6, 2017 | 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.… | ||
| CVE-2017-6594 | Hig | 0.49 | 7.5 | 0.02 | Aug 28, 2017 | 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-2018-5731 | Hig | 0.46 | 7.0 | 0.00 | Mar 22, 2018 | An issue was discovered in Heimdal PRO 2.2.190. As part of the scanning feature, a process called md.hs writes an executable called CS1.tmp to C:\windows\TEMP. Afterwards the executable is run. It is possible for an attacker to create the file first, let md.hs overwrite it, and… | ||

| CVE-2022-3116 | 0.00 | — | 0.01 | Mar 27, 2023 | The Heimdal Software Kerberos 5 implementation is vulnerable to a null pointer dereferance. An attacker with network access to an application that depends on the vulnerable code path can cause the application to crash. | |||
| CVE-2022-45142 | 0.00 | — | 0.00 | Mar 6, 2023 | The fix for CVE-2022-3437 included changing memcmp to be constant time and a workaround for a compiler bug by adding "!= 0" comparisons to the result of memcmp. When these patches were backported to the heimdal-7.7.1 and heimdal-7.8.0 branches (and possibly other branches) a… | |||
| CVE-2022-3437 | 0.00 | — | 0.04 | Jan 12, 2023 | A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and unwrap_des3() routines of Heimdal.
