Synopsis

Multiple vulnerabilities have been discovered in MIT Kerberos 5, allowing execution of arbitrary code or Denial of Service.

Background

MIT Kerberos 5 is a suite of applications that implement the Kerberos network protocol.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-crypt/mit-krb5	< 1.11.4	>= 1.11.4	All supported architectures

Description

Multiple vulnerabilities have been discovered in the Key Distribution Center in MIT Kerberos 5. Please review the CVE identifiers referenced below for details.

Impact

A remote attacker could send a specially crafted request, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition. Additionally, a remote attacker could impersonate a kadmind server and send a specially crafted packet to the password change port, which can result in a ping-pong condition and a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All MIT Kerberos 5 users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.11.4"
