Gentoo Linux Security Advisory

Title: MIT Kerberos 5: Arbitrary Remote Code Execution (GLSA 200701-21)
Severity: high
Exploitable: remote
Date: January 24, 2007
Bug(s): #158810
ID: 200701-21

Synopsis


Multiple vulnerabilities in MIT Kerberos 5 could potentially result in the
execution of arbitrary code.


Background


MIT Kerberos 5 is a suite of applications that implement the Kerberos
network protocol.


Affected Packages

Package: app-crypt/mit-krb5
Vulnerable: < 1.5.2
Unaffected: >= 1.5.2
Architectures: All supported architectures


Description


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
pointer.


Impact


A remote attacker may be able to crash an affected application, or
potentially execute arbitrary code with root privileges.


Workaround


There is no known workaround at this time.


Resolution


All MIT Kerberos 5 users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.5.2"
