このwiresharkバージョン2.2.12への更新により、以下の問題を修正します：

  - CVE-2018-5334：IxVeriWaveファイルがクラッシュする可能性があります（bsc#1075737）

  - CVE-2018-5335：WCPディセクタはクラッシュする可能性があります（bsc#1075738）。

  - CVE-2018-5336：複数のディセクタがクラッシュします（bsc#1075739）

  - CVE-2017-17935：file_read_line関数の「\n」の不適切な処理により、サービス拒否が発生する可能性があります。（bsc#1074171）このリリースでは、net.core.bpf_jit_enable sysctlを介してLinuxカーネルのBPF JITコンパイラを有効化しなくなりますが、これはシステムのSpectreバリアント1 CVE-2017-5753 -（bsc#1075748）への脆弱性が高くなるからです。追加的なバグ修正と更新済みプロトコルは、以下の通りサポートされます：

多人在从网络中捕获和分析数据包的工具 wireshark 中发现多个问题。这些问题主要是不同解析器中的长度检查或无效内存访问。通过恶意数据包，这些问题可能会造成无限循环或崩溃。对于 Debian 8“Jessie”，这些问题已在 1.12.1+g01b65bf-4+deb8u16 版本中修复。建议您升级 wireshark 程序包。注意：Tenable Network Security 已直接从 DLA 安全公告中提取上述描述块。Tenable 已尝试在不引入其他问题的情况下，尽可能进行自动整理和排版。

This update for wireshark to version 2.2.12 fixes the following issues :

  - CVE-2018-5334: IxVeriWave file could crash (bsc#1075737)

  - CVE-2018-5335: WCP dissector could crash (bsc#1075738)

  - CVE-2018-5336: Multiple dissector crashes (bsc#1075739)

  - CVE-2017-17935: Incorrect handling of '\n' in     file_read_line function could have lead to denial of     service (bsc#1074171) This release no longer enables the     Linux kernel BPF JIT compiler via the     net.core.bpf_jit_enable sysctl, as this would make     systems more vulnerable to Spectre variant 1     CVE-2017-5753 - (bsc#1075748) Further bug fixes and     updated protocol support as listed in:
    https://www.wireshark.org/docs/relnotes/wireshark-2.2.12     .html

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wireshark: free operation on an uninitialized memory address in wiretap/netmon.c (CVE-2018-6836)

  - The srtp_add_address function in epan/dissectors/packet-rtp.c in the RTP dissector in Wireshark 1.10.x     before 1.10.7 does not properly update SRTP conversation data, which allows remote attackers to cause a     denial of service (application crash) via a crafted packet. (CVE-2014-2907)

  - The dissect_frame function in epan/dissectors/packet-frame.c in the frame metadissector in Wireshark     1.10.x before 1.10.8 interprets a negative integer as a length value even though it was intended to     represent an error condition, which allows remote attackers to cause a denial of service (application     crash) via a crafted packet. (CVE-2014-4020)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wireshark: free operation on an uninitialized memory address in wiretap/netmon.c (CVE-2018-6836)

  - Stack consumption vulnerability in the dissect_ber_choice function in the BER dissector in Wireshark 1.2.x     through 1.2.15 and 1.4.x through 1.4.4 might allow remote attackers to cause a denial of service (infinite     loop) via vectors involving self-referential ASN.1 CHOICE values. (CVE-2011-1142)

  - The dissector-table implementation in epan/packet.c in Wireshark 1.12.x before 1.12.7 mishandles table     searches for empty strings, which allows remote attackers to cause a denial of service (application crash)     via a crafted packet, related to the (1) dissector_get_string_handle and (2)     dissector_get_default_string_handle functions. (CVE-2015-6243)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wireshark: free operation on an uninitialized memory address in wiretap/netmon.c (CVE-2018-6836)

  - Stack consumption vulnerability in the dissect_ber_choice function in the BER dissector in Wireshark 1.2.x     through 1.2.15 and 1.4.x through 1.4.4 might allow remote attackers to cause a denial of service (infinite     loop) via vectors involving self-referential ASN.1 CHOICE values. (CVE-2011-1142)

  - Multiple integer overflows in Wireshark 1.4.x before 1.4.13 and 1.6.x before 1.6.8 allow remote attackers     to cause a denial of service (infinite loop) via vectors related to the (1) BACapp and (2) Bluetooth HCI     dissectors, a different vulnerability than CVE-2012-2392. (CVE-2012-3825)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

不同的人在 wireshark (一種可離線擷取和分析封包的工具) 中發現數個問題。這些問題基本上是長度檢查或不同解剖器中的無效記憶體存取。惡意封包可透過這些問題導致無限迴圈或損毀。針對 Debian 8「Jessie」，這些問題已在 1.12.1+g01b65bf-4+deb8u16 版本中修正。建議您升級 wireshark 套件。注意：Tenable Network Security 已直接從 DLA 安全性公告擷取前置描述區塊。Tenable 已盡量在不造成其他問題的前提下，嘗試自動清理並將其格式化。

CVE-2017-17935 のセキュリティ修正、2.4.4 にリベース

パケットをキャプチャし、オフラインで分析するツールのwiresharkに複数の問題があることが、さまざまなユーザーによって発見されました。これらは、基本的に長さチェックの問題、または異なるディセクターの無効なメモリアクセスの問題です。これにより、悪意のあるパケットによる無限ループまたはクラッシュが発生する可能性があります。

Debian 8「Jessie」では、これらの問題はバージョン1.12.1+g01b65bf-4+deb8u16で修正されました。

wiresharkパッケージをアップグレードすることをお勧めします。

Security fix for CVE-2017-17935, rebase to 2.4.4

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several issues in wireshark, a tool that captures and analyzes packets off the wire, have been found by different people. These are basically issues with length checks or invalid memory access in different dissectors. This could result in infinite loops or crashes by malicious packets.

For Debian 8 'Jessie', these problems have been fixed in version 1.12.1+g01b65bf-4+deb8u16.

We recommend that you upgrade your wireshark packages.
