Vulnerability Assessment Details
MIT krb5: Multiple vulnerabilities
Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200409-09
(MIT krb5: Multiple vulnerabilities)
The implementation of the Key Distribution Center (KDC) and the MIT krb5
library contain double-free vulnerabilities, making client programs as well
as application servers vulnerable.
The ASN.1 decoder library is vulnerable to a denial of service attack,
including the KDC.
The double-free vulnerabilities could permit a possible hacker to execute
arbitrary code on a KDC host and hosts running krb524d or vulnerable
services. In the case of a KDC host, this can lead to a compromise of the
entire Kerberos realm. Furthermore, a possible hacker impersonating a legitimate
KDC or application server can potentially execute arbitrary code on
A possible hacker can cause a denial of service for a KDC or application server
and clients, the latter if impersonating a legitimate KDC or application
There is no known workaround at this time.
All mit-krb5 users should upgrade to the latest stable version:
# emerge sync
# emerge -pv ">=app-crypt/mit-krb5-1.3.4"
# emerge ">=app-crypt/mit-krb5-1.3.4"
