There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - cairo 1.16.0, in cairo_ft_apply_variations() in cairo-ft-font.c, would free memory using a free function
    incompatible with WebKit's fastMalloc, leading to an application crash with a "free(): invalid pointer"
    error. (CVE-2018-19876)

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且廠商未提供可用的修補程式。

  - cairo-ft-font.c 的 cairo_ft_apply_variations() 中的 cairo 1.16.0會使用與 WebKit fastMalloc 不相容的釋放函式釋放記憶體進而導致應用程式因 free():無效指標錯誤而損毀。 (CVE-2018-19876)

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - cairo 1.16.0在 cairo-ft-font.c 的 cairo_ft_apply_variations() 中会使用与 WebKit 的 fastMalloc 不兼容的释放函数来释放内存导致应用程序因 free(): 无效指针错误而崩溃。 (CVE-2018-19876)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

この更新プログラムでは、freetypeのデフォルトのLCDフィルターを使用してテキストのサブピクセルレンダリングを有効にしたとき、グリフ周辺のカラーアーチファクトを低減します。

また、メモリの解放に誤った関数を使用することで発生するクラッシュも修正されます（CVE-2018-19876）。

注意：Tenable Network Securityは、前述の記述ブロックをFedora更新システムのWebサイトから直接抽出しています。
Tenableでは、新たな問題を持ち込まずに、できる限り自動的に整理して書式設定するようにしています。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - cairo-ft-font.c の cairo_ft_apply_variations() で、cairo 1.16.0は、WebKit の fastMalloc と互換性のない解放関数を使用してメモリを解放し、free(): 無効なポインターエラーでアプリケーションのクラッシュを引き起こします。CVE-2018-19876

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

An update of the cairo package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - cairo 1.16.0, in cairo_ft_apply_variations() in cairo-ft-font.c, would free memory using a free function     incompatible with WebKit's fastMalloc, leading to an application crash with a free(): invalid pointer     error. (CVE-2018-19876)

Note that Nessus relies on the presence of the package as reported by the vendor.

This update lowers amount of color artefacts around glyphs when subpixel rendering is enabled for text by using freetype's default LCD filter.

It also fixes a crash caused by using of wrong function for freeing of memory (CVE-2018-19876).

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.

According to the version of the cairo package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - cairo 1.16.0, in cairo_ft_apply_variations() in     cairo-ft-font.c, would free memory using a free     function incompatible with WebKit's fastMalloc, leading     to an application crash with a 'free(): invalid     pointer' error.(CVE-2018-19876)
