mit-krb5: Heap overflow in libkadm5srv — GLSA 200501-05

The MIT Kerberos 5 administration library (libkadm5srv) contains a heap overflow that could lead to execution of arbitrary code.

Package	app-crypt/mit-krb5 on all architectures
Affected versions	< 1.3.6
Unaffected versions	>= 1.3.6

MIT krb5 is the free implementation of the Kerberos network authentication protocol by the Massachusetts Institute of Technology.

The MIT Kerberos 5 administration library libkadm5srv contains a heap overflow in the code handling password changing.

Under specific circumstances an attacker could execute arbitary code with the permissions of the user running mit-krb5, which could be the root user.

There is no known workaround at this time.

All mit-krb5 users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.3.6"
