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 < 1.9.2-r1 >= 1.9.2-r1 Description =========== Multiple vulnerabilities have been discovered in MIT Kerberos 5. Please review the CVE identifiers referenced below for details. Impact ====== A remote attacker may be able to execute arbitrary code with the privileges of the administration daemon or the Key Distribution Center (KDC) daemon, cause a Denial of Service condition, or possibly obtain sensitive information. Furthermore, a remote attacker may be able to spoof Kerberos authorization, modify KDC responses, forge user data messages, forge tokens, forge signatures, impersonate a client, modify user-visible prompt text, or have other unspecified impact. 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-krb5-1.9.2-r1" References ========== [ 1 ] CVE-2009-3295 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3295 [ 2 ] CVE-2009-4212 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-4212 [ 3 ] CVE-2010-0283 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-0283 [ 4 ] CVE-2010-0629 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-0629 [ 5 ] CVE-2010-1320 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-1320 [ 6 ] CVE-2010-1321 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-1321 [ 7 ] CVE-2010-1322 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-1322 [ 8 ] CVE-2010-1323 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-1323 [ 9 ] CVE-2010-1324 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-1324 [ 10 ] CVE-2010-4020 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-4020 [ 11 ] CVE-2010-4021 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-4021 [ 12 ] CVE-2010-4022 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-4022 [ 13 ] CVE-2011-0281 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-0281 [ 14 ] CVE-2011-0282 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-0282 [ 15 ] CVE-2011-0283 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-0283 [ 16 ] CVE-2011-0284 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-0284 [ 17 ] CVE-2011-0285 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-0285 [ 18 ] CVE-2011-1527 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1527 [ 19 ] CVE-2011-1528 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1528 [ 20 ] CVE-2011-1529 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1529 [ 21 ] CVE-2011-1530 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1530 [ 22 ] CVE-2011-4151 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-4151 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201201-13.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
