In particular, there is a corner case where the off\n reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1185847\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1186061\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1186285\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1186498\");\n script_set_attribute(attribute:\"see_also\", value:\"https://www.suse.com/security/cve/CVE-2021-23134\");\n script_set_attribute(attribute:\"see_also\", value:\"https://www.suse.com/security/cve/CVE-2021-33034\");\n script_set_attribute(attribute:\"see_also\", value:\"https://www.suse.com/security/cve/CVE-2021-33200\");\n # https://lists.suse.com/pipermail/sle-security-updates/2021-June/009046.html\n script_set_attribute(attribute:\"see_also\", value:\"http://www.nessus.org/u?fb2ac96b\");\n script_set_attribute(attribute:\"solution\", value:\n\"Update the affected kernel-livepatch-5_3_18-24_64-default package.\");\n script_set_cvss_base_vector(\"CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C\");\n script_set_cvss_temporal_vector(\"CVSS2#E:POC/RL:OF/RC:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H\");\n script_set_cvss3_temporal_vector(\"CVSS:3.0/E:P/RL:O/RC:C\");\n script_set_attribute(attribute:\"cvss_score_source\", value:\"CVE-2021-33200\");\n\n script_set_attribute(attribute:\"exploitability_ease\", value:\"Exploits are available\");\n script_set_attribute(attribute:\"exploit_available\", value:\"true\");\n\n script_set_attribute(attribute:\"vuln_publication_date\", value:\"2021/05/12\");\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2021/06/18\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2021/06/21\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:novell:suse_linux:kernel-livepatch-5_3_18-24_64-default\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:novell:suse_linux:15\");\n script_set_attribute(attribute:\"generated_plugin\", value:\"current\");\n script_end_attributes();\n\n script_category(ACT_GATHER_INFO);\n script_family(english:\"SuSE Local Security Checks\");\n\n script_copyright(english:\"This script is Copyright (C) 2021-2023 and is owned by Tenable, Inc. or an Affiliate thereof.\");\n\n script_dependencies(\"ssh_get_info.nasl\");\n script_require_keys(\"Host/local_checks_enabled\", \"Host/cpu\", \"Host/SuSE/release\", \"Host/SuSE/rpm-list\");\n\n exit(0);\n}\n\n\ninclude('rpm.inc');\n\nif (!get_kb_item('Host/local_checks_enabled')) audit(AUDIT_LOCAL_CHECKS_NOT_ENABLED);\nvar os_release = get_kb_item(\"Host/SuSE/release\");\nif (isnull(os_release) || os_release !~ \"^(SLED|SLES)\") audit(AUDIT_OS_NOT, \"SUSE\");\nvar os_ver = pregmatch(pattern: \"^(SLE(S|D)\\d+)\", string:os_release);\nif (isnull(os_ver)) audit(AUDIT_UNKNOWN_APP_VER, 'SUSE');\nos_ver = os_ver[1];\nif (!
