Severity: high

Date: January 05, 2005
Bug(s): #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: app-crypt/mit-krb5
Vulnerable: < 1.3.6
Unaffected: >= 1.3.6
Architectures: 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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.3.6"
