|app-crypt/mit-krb5 on all architectures
MIT Kerberos 5 is a suite of applications that implement the Kerberos network protocol.
Multiple vulnerabilities have been discovered in the Key Distribution Center in MIT Kerberos 5. Please review the CVE identifiers referenced below for details.
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.
There is no known workaround at this time.
All MIT Kerberos 5 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.11.4"
