This update was imported from the SUSE:SLE-12:Update update project.

The following packages have been upgraded to a later upstream version:
tcpdump (4.9.0).

Security Fix(es) :

  - Multiple out of bounds read and integer overflow     vulnerabilities were found in tcpdump affecting the     decoding of various protocols. An attacker could create     a crafted pcap file or send specially crafted packets to     the network segment where tcpdump is running in live     capture mode (without -w) which could cause it to     display incorrect data, crash or enter an infinite loop.

An update for tcpdump is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The tcpdump packages contain the tcpdump utility for monitoring network traffic. The tcpdump utility can capture and display the packet headers on a particular network interface or on all interfaces.

The following packages have been upgraded to a later upstream version:
tcpdump (4.9.0). (BZ#1422473)

現已提供適用於 Red Hat Enterprise Linux 7 的 tcpdump 更新。Red Hat 產品安全性團隊已將此更新評等為具有中等安全性影響。可從〈參照〉一節的 CVE 連結中取得每個弱點之常見弱點評分系統 (CVSS) 的基本分數，其中包含有關嚴重性評等的詳細資訊。Tcpdump 套件包含可監視網路流量的 tcpdump 公用程式。Tcpdump 公用程式可擷取和顯示特定網路介面或所有介面上的封包標頭。下列套件已升級至更新的上游版本：tcpdump (4.9.0)。(BZ#1422473) 安全性修正：* 在 tcpdump 中發現多個超出邊界讀取和整數溢位弱點，影響到不同通訊協定的解碼。攻擊者可建立特製的 pcap 檔案或將特製的封包傳送到正以即時擷取模式 (無 -w) 執行 tcpdump 的網段，因而造成顯示錯誤資料、當機或進入無限迴圈。(CVE-2015-0261、CVE-2015-2153、CVE-2015-2154、CVE-2015-2155、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-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) Red Hat 感謝 Tcpdump 專案報告 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-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 及 CVE-2017-5486。其他變更：如需有關此發行版本的詳細變更資訊，請參閱可從〈參照〉一節連結的 Red Hat Enterprise Linux 7.4 版本資訊。

現已提供適用於 Slackware 13.37、14.0、14.1、14.2 和最新版本的新 tcpdump 套件，可修正多個安全性問題。注意：這些更新也需要使用已更新的 libpcap 套件。

遠端主機執行的 macOS 是 10.12.4 之前的 10.12.x 版。因此會受到多個元件中的多個弱點影響，其中有些是遠端程式碼執行弱點。未經驗證的遠端攻擊者可惡意利用這些遠端程式碼執行弱點，誘騙使用者造訪特製的網站，進而導致在目前使用者的內容中執行任意程式碼。受影響的元件如下：- 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
