Date:	01/05/2005
Bugs:	#75143
ID:	200501-05

Synopsis

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

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-crypt/mit-krb5	< 1.3.6	>= 1.3.6	All supported architectures

Description

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

Impact

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

Workaround

There is no known workaround at this time.

Resolution

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

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