Common Vulnerability Scoring System (CVSS) base\nscores, which give detailed severity ratings, are available for each\nvulnerability from the CVE links in the References section.\n\nKerberos is a network authentication system, which can improve the\nsecurity of your network by eliminating the insecure practice of\nsending passwords over the network in unencrypted form. It allows\nclients and servers to authenticate to each other with the help of a\ntrusted third party, the Kerberos key distribution center (KDC).\n\nIt was found that the krb5_read_message() function of MIT Kerberos did\nnot correctly sanitize input, and could create invalid krb5_data\nobjects. A remote, unauthenticated attacker could use this flaw to\ncrash a Kerberos child process via a specially crafted request.\n(CVE-2014-5355)\n\nA flaw was found in the OTP kdcpreauth module of MIT kerberos. An\nunauthenticated remote attacker could use this flaw to bypass the\nrequires_preauth flag on a client principal and obtain a ciphertext\nencrypted in the principal's long-term key. This ciphertext could be\nused to conduct an off-line dictionary attack against the user's\npassword. (CVE-2015-2694)\n\nThe krb5 packages have been upgraded to upstream version 1.13.2, which\nprovides a number of bug fixes and enhancements over the previous\nversion. (BZ#1203889)\n\nNotably, this update fixes the following bugs :\n\n* Previously, the RADIUS support (libkrad) in krb5 was sending krb5\nauthentication for Transmission Control Protocol (TCP) transports\nmultiple times, accidentally using a code path intended to be used\nonly for unreliable transport types, for example User Datagram\nProtocol (UDP) transports. A patch that fixes the problem by disabling\nmanual retries for reliable transports, such as TCP, has been applied,\nand the correct code path is now used in this situation. (BZ#1251586)\n\n* Attempts to use Kerberos single sign-on (SSO) to access SAP\nNetWeaver systems sometimes failed. The SAP NetWeaver developer trace\ndisplayed the following error message :\n\nNo credentials were supplied, or the credentials were unavailable or\ninaccessible Unable to establish the security context\n\nQuerying SSO credential lifetime has been modified to trigger\ncredential acquisition, thus preventing the error from occurring. Now,\nthe user can successfully use Kerberos SSO for accessing SAP NetWeaver\nsystems. (BZ#1252454)\n\nAll krb5 users are advised to upgrade to these updated packages, which\ncorrect these issues and add these enhancements.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"http://rhn.redhat.com/errata/RHSA-2015-2154.html\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://www.redhat.com/security/data/cve/CVE-2014-5355.html\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://www.redhat.com/security/data/cve/CVE-2015-2694.html\"\n );\n script_set_attribute(attribute:\"solution\", value:\"Update the affected packages.\");\n script_set_cvss_base_vector(\"CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:N\");\n script_set_cvss_temporal_vector(\"CVSS2#E:U/RL:OF/RC:C\");\n script_set_attribute(attribute:\"exploitability_ease\", value:\"No known exploits are available\");\n script_set_attribute(attribute:\"exploit_available\", value:\"false\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:redhat:enterprise_linux:krb5-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:redhat:enterprise_linux:krb5-devel\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:redhat:enterprise_linux:krb5-libs\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:redhat:enterprise_linux:krb5-pkinit\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:redhat:enterprise_linux:krb5-server\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:redhat:enterprise_linux:krb5-server-ldap\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:redhat:enterprise_linux:krb5-workstation\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:redhat:enterprise_linux:7\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:redhat:enterprise_linux:7.2\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:redhat:enterprise_linux:7.3\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:redhat:enterprise_linux:7.4\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:redhat:enterprise_linux:7.5\");\n\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2015/11/19\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2015/11/19\");\n script_end_attributes();\n\n script_category(ACT_GATHER_INFO);\n script_copyright(english:\"This script is Copyright (C) 2015-2018 and is owned by Tenable, Inc. or an Affiliate thereof.\");\n script_family(english:\"Red Hat Local Security Checks\");\n\n script_dependencies(\"ssh_get_info.nasl\");\n script_require_keys(\"Host/local_checks_enabled\", \"Host/RedHat/release\", \"Host/RedHat/rpm-list\", \"Host/cpu\");\n\n exit(0);\n}\n\n\ninclude(\"audit.inc\");\ninclude(\"global_settings.inc\");\ninclude(\"misc_func.inc\");\ninclude(\"rpm.inc\");\n\nif (!get_kb_item(\"Host/local_checks_enabled\")) audit(AUDIT_LOCAL_CHECKS_NOT_ENABLED);\nrelease = get_kb_item(\"Host/RedHat/release\");\nif (isnull(release) || \"Red Hat\" >!< release) audit(AUDIT_OS_NOT, \"Red Hat\");\nos_ver = eregmatch(pattern: \"Red Hat Enterprise Linux.*release ([0-9]+(\\.[0-9]+)?)\", string:release);\nif (isnull(os_ver)) audit(AUDIT_UNKNOWN_APP_VER, \"Red Hat\");\nos_ver = os_ver[1];\nif (!

The SAP NetWeaver developer trace displayed the\nfollowing error message:\n\n No credentials were supplied, or the credentials were\n unavailable or inaccessible\n Unable to establish the security context\n\nQuerying SSO credential lifetime has been modified to trigger credential\nacquisition, thus preventing the error from occurring. Now, the user can\nsuccessfully use Kerberos SSO for accessing SAP NetWeaver systems.\n(BZ#1252454)\n\nAll krb5 users are advised to upgrade to these updated packages, which\ncorrect these issues and add these enhancements.\n\");\n script_tag(name: \"affected\", value: \"krb5 on Red Hat Enterprise Linux Server (v. 7)\");\n script_tag(name: \"solution\", value: \"Please Install the Updated Packages.\");\n script_xref(name: \"RHSA\", value: \"2015:2154-07\");\n script_xref(name: \"URL\" , value: \"https://www.redhat.com/archives/rhsa-announce/2015-November/msg00026.html\");\n script_tag(name:\"solution_type\", value:\"VendorFix\");\n script_category(ACT_GATHER_INFO);\n script_copyright(\"Copyright (C) 2015 Greenbone Networks GmbH\");\n script_family(\"Red Hat Local Security Checks\");\n script_dependencies(\"gather-package-list.nasl\");\n script_mandatory_keys(\"ssh/login/rhel\", \"ssh/login/rpms\");\n exit(0);\n}\n\ninclude(\"revisions-lib.inc\");\ninclude(\"pkg-lib-rpm.inc\");\n\nrelease = get_kb_item(\"ssh/login/release\");\n\nres = \"\";\nif(release == NULL){\n exit(0);\n}\n\nif(release == \"RHENT_7\")\n{\n\n if ((res = isrpmvuln(pkg:\"krb5-debuginfo\", rpm:\"krb5-debuginfo~1.13.2~10.el7\", rls:\"RHENT_7\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"krb5-devel\", rpm:\"krb5-devel~1.13.2~10.el7\", rls:\"RHENT_7\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"krb5-libs\", rpm:\"krb5-libs~1.13.2~10.el7\", rls:\"RHENT_7\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"krb5-pkinit\", rpm:\"krb5-pkinit~1.13.2~10.el7\", rls:\"RHENT_7\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"krb5-server\", rpm:\"krb5-server~1.13.2~10.el7\", rls:\"RHENT_7\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"krb5-server-ldap\", rpm:\"krb5-server-ldap~1.13.2~10.el7\", rls:\"RHENT_7\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"krb5-workstation\", rpm:\"krb5-workstation~1.13.2~10.el7\", rls:\"RHENT_7\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if (__pkg_match) exit(99); # Not vulnerable.\n exit(0);\n}\n", "cvss": {"score": 5.8, "vector": "AV:NETWORK/AC:MEDIUM/Au:NONE/C:PARTIAL/I:PARTIAL/A:NONE/"}}, {"lastseen": "2018-09-01T23:49:54", "references": ["2810-1", "http://www.ubuntu.com/usn/usn-2810-1/"], "pluginID": "1361412562310842532", "description": "Check the version of krb5", "edition": 8, "reporter": "Copyright (C) 2015 Greenbone Networks GmbH", "published": "2015-11-13T00:00:00", "title": "Ubuntu Update for krb5 USN-2810-1", "type": "openvas", "enchantments": {"score": {"vector": "NONE", "value": 7.5}}, "naslFamily": "Ubuntu Local Security Checks", "bulletinFamily": "scanner", "cvelist": ["CVE-2015-2696", "CVE-2014-5355", "CVE-2015-2695", "CVE-2015-2697", "CVE-2015-2698", "CVE-2015-2694", "CVE-2002-2443"], "modified": "2018-08-17T00:00:00", "id": "OPENVAS:1361412562310842532", "href": "http://plugins.openvas.org/nasl.php?oid=1361412562310842532", "sourceData": "###############################################################################\n# OpenVAS Vulnerability Test\n#\n# Ubuntu Update for krb5 USN-2810-1\n#\n# Authors:\n# System Generated Check\n#\n# Copyright:\n# Copyright (C) 2015 Greenbone Networks GmbH, http://www.greenbone.net\n#\n# This program is free software; you can redistribute it and/or modify\n# it under the terms of the GNU General Public License version 2\n# (or any later version), as published by the Free Software Foundation.\n#\n# This program is distributed in the hope that it will be useful,\n# but WITHOUT ANY WARRANTY; without even the implied warranty of\n# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

the security\nof your network by eliminating the insecure practice of sending passwords\nover the network in unencrypted form. It allows clients and servers to\nauthenticate to each other with the help of a trusted third party, the\nKerberos key distribution center (KDC).\n\nIt was found that the krb5_read_message() function of MIT Kerberos did not\ncorrectly sanitize input, and could create invalid krb5_data objects.\nA remote, unauthenticated attacker could use this flaw to crash a Kerberos\nchild process via a specially crafted request. (CVE-2014-5355)\n\nA flaw was found in the OTP kdcpreauth module of MIT kerberos.\nAn unauthenticated remote attacker could use this flaw to bypass the\nrequires_preauth flag on a client principal and obtain a ciphertext\nencrypted in the principal's long-term key. This ciphertext could be used\nto conduct an off-line dictionary attack against the user's password.\n(CVE-2015-2694)\n\nThe krb5 packages have been upgraded to upstream version 1.13.2, which\nprovides a number of bug fixes and enhancements over the previous version.\n(BZ#1203889)\n\nNotably, this update fixes the following bugs:\n\n* Previously, the RADIUS support (libkrad) in krb5 was sending krb5\nauthentication for Transmission Control Protocol (TCP) transports multiple\ntimes, accidentally using a code path intended to be used only for\nunreliable transport types, for example User Datagram Protocol (UDP)\ntransports. A patch that fixes the problem by disabling manual retries for\nreliable transports, such as TCP, has been applied, and the correct code\npath is now used in this situation. (BZ#1251586)\n\n* Attempts to use Kerberos single sign-on (SSO) to access SAP NetWeaver\nsystems sometimes failed. The SAP NetWeaver developer trace displayed the\nfollowing error message:\n\n No credentials were supplied, or the credentials were\n unavailable or inaccessible\n Unable to establish the security context\n\nQuerying SSO credential lifetime has been modified to trigger credential\nacquisition, thus preventing the error from occurring. Now, the user can\nsuccessfully use Kerberos SSO for accessing SAP NetWeaver systems.\n(BZ#1252454)\n\nAll krb5 users are advised to upgrade to these updated packages, which\ncorrect these issues and add these enhancements.", "reporter": "RedHat", "published": "2015-11-19T19:40:51", "type": "redhat", "title": "(RHSA-2015:2154) Moderate: krb5 security, bug fix, and enhancement update",
