Evaluator Impact

Per: http://web.mit.edu/kerberos/advisories/MITKRB5-SA-2009-004.txt "Only releases krb5-1.3 and later are vulnerable, as earlier releases did not contain the functionality implemented by the vulnerable code. This is an implementation vulnerability in MIT krb5, and is not a vulnerability in the Kerberos protocol."

Evaluator Solution

Per: http://web.mit.edu/kerberos/advisories/MITKRB5-SA-2009-004.txt FIXES ===== * The upcoming krb5-1.7.1 and krb5-1.6.4 releases will contain a fix for this vulnerability. * For the krb5-1.7 release, apply the patch available at: http://web.mit.edu/kerberos/advisories/2009-004-patch_1.7.txt A PGP-signed patch is available at http://web.mit.edu/kerberos/advisories/2009-004-patch_1.7.txt.asc * For the krb5-1.6 releases, apply the patch available at: http://web.mit.edu/kerberos/advisories/2009-004-patch_1.6.3.txt A PGP-signed patch is available at http://web.mit.edu/kerberos/advisories/2009-004-patch_1.6.3.txt.asc * The krb5-1.6.3 patch might apply successfully to older releases.
