</p>
|
|
<ul><li>pam_krb5
|
|
does not properly initialize the Kerberos libraries for setuid use
|
|
(CVE-2009-0360).</li>
|

<impact type="high">
|
|
<p>
|
|
A local attacker could set an environment variable to point to a
|
|
specially crafted Kerberos configuration file and launch a PAM-based
|
|
setuid application to elevate privileges, or change ownership and
|
|
overwrite arbitrary files.

</impact>
|
|
<workaround>

<p>
|
|
There is no known workaround at this time.
