    Several local vulnerabilities have been discovered in the  PAM module
    for MIT Kerberos. The Common Vulnerabilities and Exposures project
    identifies the following problems:
    
    CVE-2009-0360
    
       Russ Allbery discovered that the Kerberos PAM module parsed
       configuration settings from enviromnent variables when run from a
       setuid context. This could lead to local privilege escalation if
       an attacker points a setuid program using PAM authentication to a
       Kerberos setup under her control.
    
    CVE-2009-0361
    
       Derek Chan discovered that the Kerberos PAM module allows
       reinitialisation of user credentials when run from a setuid
       context, resulting in potential local denial of service by
       overwriting the credential cache file or to privilege escalation.
    
    For the stable distribution (etch), these problems have been fixed in
    version 2.6-1etch1.
    
    For the upcoming stable distribution (lenny), these problems have been
    fixed in version 3.11-4.
    
    For the unstable distribution (sid), these problems will be fixed soon.
    
    We recommend that you upgrade your libpam-krb5 package.
