Summary
Gentoo Linux Security Advisory GLSA 200707-11
https://security.gentoo.org/
Severity: High
Title: MIT Kerberos 5: Arbitrary remote code execution
Date: July 25, 2007
Bugs: #183338
ID: 200707-11
Synopsis
=======
Multiple vulnerabilities in MIT Kerberos 5 could potentially result in
remote code execution with root privileges by unauthenticated users.
Background
=========
MIT Kerberos 5 is a suite of applications that implement the Kerberos
network protocol.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-crypt/mit-krb5 < 1.5.2-r3 >= 1.5.2-r3
==========
kadmind is affected by multiple vulnerabilities in the RPC library
shipped with MIT Kerberos 5. It fails to properly handle zero-length
RPC credentials (CVE-2007-2442) and the RPC library can write past the
end of the stack buffer (CVE-2007-2443). Furthermore kadmind fails to
do proper bounds checking (CVE-2007-2798).
Impact
=====
A remote unauthenticated attacker could exploit these vulnerabilities
to 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:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.5.2-r3"
