EulerOS 2.0 SP2 : krb5 (EulerOS-SA-2018-1354)
Medium Nessus Plugin ID 118737
SynopsisThe remote EulerOS host is missing multiple security updates.
DescriptionAccording to the versions of the krb5 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
- A denial of service flaw was found in MIT Kerberos krb5kdc service. An authenticated attacker could use this flaw to cause krb5kdc to exit with an assertion failure by making an invalid S4U2Self or S4U2Proxy request.(CVE-2017-11368)
- An authentication bypass flaw was found in the way krb5's certauth interface 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-2017-7562)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected krb5 packages.
