MIT Kerberos 5 is a suite of applications that implement the Kerberos
network protocol.
The Kerberos administration daemon, and possibly other applications
using the GSS-API or RPC libraries, could potentially call a function
pointer in a freed heap buffer, or attempt to free an uninitialized
<impact type="high">
A remote attacker may be able to crash an affected application, or
potentially execute arbitrary code with root privileges.
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 &quot;&gt;=app-crypt/mit-krb5-1.5.2&quot;</code>
