NASL family MacOS X Local Security Checks NASL id MACOS_10_12_4.NASL description The remote host is running a version of macOS that is 10.12.x prior to 10.12.4. It is, therefore, affected by multiple vulnerabilities in multiple components, some of which are remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these remote code execution vulnerabilities by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user. The affected components are as follows : - apache - apache_mod_php - AppleGraphicsPowerManagement - AppleRAID - Audio - Bluetooth - Carbon - CoreGraphics - CoreMedia - CoreText - curl - EFI - FinderKit - FontParser - HTTPProtocol - Hypervisor - iBooks - ImageIO - Intel Graphics Driver - IOATAFamily - IOFireWireAVC - IOFireWireFamily - Kernel - Keyboards - libarchive - libc++abi - LibreSSL - MCX Client - Menus - Multi-Touch - OpenSSH - OpenSSL - Printing - python - QuickTime - Security - SecurityFoundation - sudo - System Integrity Protection - tcpdump - tiffutil - WebKit last seen 2020-06-01 modified 2020-06-02 plugin id 99134 published 2017-03-31 reporter This script is Copyright (C) 2017-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/99134 title macOS 10.12.x < 10.12.4 Multiple Vulnerabilities (httpoxy) code # # (C) Tenable Network Security, Inc. # include("compat.inc"); if (description) { script_id(99134); script_version("1.9"); script_cvs_date("Date: 2019/11/13"); script_cve_id( "CVE-2016-0736", "CVE-2016-2161", "CVE-2016-3619", "CVE-2016-4688", "CVE-2016-5387", "CVE-2016-5636", "CVE-2016-7056", "CVE-2016-7585", "CVE-2016-7922", "CVE-2016-7923", "CVE-2016-7924", "CVE-2016-7925", "CVE-2016-7926", "CVE-2016-7927", "CVE-2016-7928", "CVE-2016-7929", "CVE-2016-7930", "CVE-2016-7931", "CVE-2016-7932", "CVE-2016-7933", "CVE-2016-7934", "CVE-2016-7935", "CVE-2016-7936", "CVE-2016-7937", "CVE-2016-7938", "CVE-2016-7939", "CVE-2016-7940", "CVE-2016-7973", "CVE-2016-7974", "CVE-2016-7975", "CVE-2016-7983", "CVE-2016-7984", "CVE-2016-7985", "CVE-2016-7986", "CVE-2016-7992", "CVE-2016-7993", "CVE-2016-8574", "CVE-2016-8575", "CVE-2016-8740", "CVE-2016-8743", "CVE-2016-9533", "CVE-2016-9535", "CVE-2016-9536", "CVE-2016-9537", "CVE-2016-9538", "CVE-2016-9539", "CVE-2016-9540", "CVE-2016-9586", "CVE-2016-9935", "CVE-2016-10009", "CVE-2016-10010", "CVE-2016-10011", "CVE-2016-10012", "CVE-2016-10158", "CVE-2016-10159", "CVE-2016-10160", "CVE-2016-10161", "CVE-2017-2379", "CVE-2017-2381", "CVE-2017-2388", "CVE-2017-2390", "CVE-2017-2398", "CVE-2017-2401", "CVE-2017-2402", "CVE-2017-2403", "CVE-2017-2406", "CVE-2017-2407", "CVE-2017-2408", "CVE-2017-2409", "CVE-2017-2410", "CVE-2017-2413", "CVE-2017-2416", "CVE-2017-2417", "CVE-2017-2418", "CVE-2017-2420", "CVE-2017-2421", "CVE-2017-2422", "CVE-2017-2423", "CVE-2017-2425", "CVE-2017-2426", "CVE-2017-2427", "CVE-2017-2428", "CVE-2017-2429", "CVE-2017-2430", "CVE-2017-2431", "CVE-2017-2432", "CVE-2017-2435", "CVE-2017-2436", "CVE-2017-2437", "CVE-2017-2438", "CVE-2017-2439", "CVE-2017-2440", "CVE-2017-2441", "CVE-2017-2443", "CVE-2017-2448", "CVE-2017-2449", "CVE-2017-2450", "CVE-2017-2451", "CVE-2017-2456", "CVE-2017-2458", "CVE-2017-2461", "CVE-2017-2462", "CVE-2017-2467", "CVE-2017-2472", "CVE-2017-2473", "CVE-2017-2474", "CVE-2017-2477", "CVE-2017-2478", "CVE-2017-2482", "CVE-2017-2483", "CVE-2017-2485", "CVE-2017-2487", "CVE-2017-2489", "CVE-2017-2490", "CVE-2017-5029", "CVE-2017-5202", "CVE-2017-5203", "CVE-2017-5204", "CVE-2017-5205", "CVE-2017-5341", "CVE-2017-5342", "CVE-2017-5482", "CVE-2017-5483", "CVE-2017-5484", "CVE-2017-5485", "CVE-2017-5486", "CVE-2017-6974", "CVE-2017-7070" ); script_bugtraq_id( 85919, 91247, 91816, 94572, 94650, 94742, 94744, 94745, 94746, 94747, 94753, 94754, 94846, 94968, 94972, 94975, 94977, 95019, 95076, 95077, 95078, 95375, 95764, 95768, 95774, 95783, 95852, 96767, 97132, 97134, 97137, 97140, 97146, 97147, 97300, 97301, 97303 ); script_xref(name:"APPLE-SA", value:"APPLE-SA-2017-03-27-3"); script_xref(name:"CERT", value:"797896"); script_xref(name:"EDB-ID", value:"40961"); script_xref(name:"EDB-ID", value:"40962"); script_name(english:"macOS 10.12.x < 10.12.4 Multiple Vulnerabilities (httpoxy)"); script_summary(english:"Checks the version of macOS."); script_set_attribute(attribute:"synopsis", value: "The remote host is missing a macOS update that fixes multiple security vulnerabilities."); script_set_attribute(attribute:"description", value: "The remote host is running a version of macOS that is 10.12.x prior to 10.12.4.

A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS as other releases were fixed in a previous security update. (CVE-2016-2177) It was discovered that OpenSSL did not properly handle Montgomery multiplication, resulting in incorrect results leading to transient failures. This issue only applied to Ubuntu 16.04 LTS, and Ubuntu 16.10. (CVE-2016-7055) It was discovered that OpenSSL did not properly use constant-time operations when performing ECDSA P-256 signing. A remote attacker could possibly use this issue to perform a timing attack and recover private ECDSA keys. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2016-7056) Shi Lei discovered that OpenSSL incorrectly handled certain warning alerts. A remote attacker could possibly use this issue to cause OpenSSL to stop responding, resulting in a denial of service. (CVE-2016-8610) Robert Swiecki discovered that OpenSSL incorrectly handled certain truncated packets. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2017-3731) It was discovered that OpenSSL incorrectly performed the x86_64 Montgomery squaring procedure. While unlikely, a remote attacker could possibly use this issue to recover private keys. This issue only applied to Ubuntu 16.04 LTS, and Ubuntu 16.10. (CVE-2017-3732).

It is therefore, affected by multiple vulnerabilities : - An information disclosure vulnerability exists in the LibreSSL component due to a flaw in the ECDSA implementation that is triggered when not properly setting a flag in ECDSA signing nonces to indicate that only constant-time code paths should be followed. An unauthenticated, remote attacker can exploit this to conduct side-channel cache-timing attacks, allowing the attacker to recover the modular inversion state sequences and the ECDSA private keys. Note that this vulnerability does not affect Mac OS X 10.10.5. (CVE-2016-7056) - An integer overflow condition exists in the ImageIO component due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted JPEG file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-2432) - Multiple memory corruption issues exist in the libxslt component that allow an unauthenticated, remote attacker to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-2477) - An integer overflow condition exists in the libxslt component in the xsltAddTextString() function in transform.c. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted file, to cause an out-of-bounds write, potentially allowing the execution of arbitrary code.

Security Fix(es) : * A memory leak flaw was found in the way OpenSSL handled TLS status request extension data during session renegotiation. A remote attacker could cause a TLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory, if it enabled OCSP stapling support. (CVE-2016-6304) * It was discovered that the mod_session_crypto module of httpd did not use any mechanisms to verify integrity of the encrypted session data stored in the user last seen 2020-06-01 modified 2020-06-02 plugin id 117316 published 2018-09-06 reporter This script is Copyright (C) 2018-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/117316 title RHEL 6 : JBoss Core Services (RHSA-2017:1414) NASL family SuSE Local Security Checks NASL id OPENSUSE-2017-255.NASL description This update for openssl fixes the following issues contained in the OpenSSL Security Advisory [26 Jan 2017] (bsc#1021641) Security issues fixed : - CVE-2016-7056: A local ECSDA P-256 timing attack that might have allowed key recovery was fixed (bsc#1019334) - CVE-2016-8610: A remote denial of service in SSL alert handling was fixed (bsc#1005878) - CVE-2016-2108: Added a missing commit for CVE-2016-2108, fixing the negative zero handling in the ASN.1 decoder (bsc#1004499) - CVE-2017-3731: Truncated packet could crash via OOB read (bsc#1022085, CVE-2017-3731) - Degrade the 3DES cipher to MEDIUM in SSLv2 (bsc#1001912) Bugs fixed : - fix crash in openssl speed (bsc#1000677) - fix ca-bundle path (bsc#1022271) This update was imported from the SUSE:SLE-12-SP1:Update update project. last seen 2020-06-05 modified 2017-02-21 plugin id 97275 published 2017-02-21 reporter This script is Copyright (C) 2017-2020 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/97275 title openSUSE Security Update : openssl (openSUSE-2017-255)
