EulerOS Virtualization for ARM 64 3.0.1.0 : krb5 (EulerOS-SA-2019-1383)

According to the versions of the krb5 packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities : - MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to...

Denial Of Service (DoS)

Kerberos is a networked authentication system which allows clients and servers to authenticate to each other with the help of a trusted third party, the Kerberos KDC. A memory leak flaw was found in the krb5unparsename function of the MIT Kerberos kadmind service. An authenticated attacker could...

Privilege Escalation

Kerberos is vulnerable to privilege escalation. The the MIT Kerberos administration server kadmind incorrectly accepted certain authentication requests for two-component server principal names. A remote attacker able to acquire a key with a particularly named principal such as "kad/x" could use...

Arbitrary Code Execution

Kerberos is a networked authentication system which allows clients and servers to authenticate to each other with the help of a trusted third party, the Kerberos KDC. The following security issues are fixed with this release: A use-after-free flaw was found in the way the MIT Kerberos libgssapikr...

HostHunter - A Recon Tool For Discovering Hostnames Using OSINT Techniques

A tool to efficiently discover and extract hostnames over a large set of target IP addresses. HostHunter utilises simple OSINT techniques. It generates a CSV file containing the results of the reconnaissance. Taking screenshots was also added as a beta functionality. Demo Currently GitLab's marku...

EulerOS Virtualization 2.5.3 : krb5 (EulerOS-SA-2019-1167)

According to the versions of the krb5 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - An authentication bypass flaw was found in the way krb5's certauth interface handled the validation of client certificates. A remot...

Debian DLA-1643-1 : krb5 security update

krb5, a MIT Kerberos implementation, had several flaws in LDAP DN checking, which could be used to circumvent a DN containership check by supplying special parameters to some calls. Further an attacker could crash the KDC by making S4U2Self requests. For Debian 8 'Jessie', these problems have bee...

Amazon Linux AMI : krb5 (ALAS-2018-1129)

MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to circumvent a DN containership check by supplying both a 'linkdn' and 'containerdn' database argument, or by supplying a DN string which is a left extension of a container DN stri...

Low: krb5

Issue Overview: MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to circumvent a DN containership check by supplying both a "linkdn" and "containerdn" database argument, or by supplying a DN string which is a left extension of a...

Denial Of Service (DoS)

krb5 is vulnerable to denial of service DoS attacks. The vulnerability exists as the pkinitserverreturnpadata function in plugins/preauth/pkinit/pkinitsrv.c in the PKINIT implementation in the Key Distribution Center KDC in MIT Kerberos 5 aka krb5 before 1.10.4 attempts to find an agility KDF...

Denial Of Service (DoS)

krb5 is vulnerable to denial of service DoS attacks. The vulnerability exists as schpw.c in the kpasswd service in kadmind in MIT Kerberos 5 aka krb5 before 1.11.3 does not properly validate UDP packets before sending responses, which allows remote attackers to cause a denial of service CPU and...

CVE-2018-20217

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-2018-20217

CVE-2018-20217 affects MIT Kerberos 5 (krb5) KDC prior to patch level; a reachable assertion can be triggered in the KDC if an attacker obtains a krbtgt ticket with an old encryption type (DES/RC4) and issues an S4U2Self request, potentially crashing the KDC. Public advisories note the vulnerabil...
