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。

  - FLTK through 1.4.5 在 Fl_BMP_Image：：load_bmp_（） 中包含堆疊型緩衝區溢位弱點，攻擊者可藉由提供過大的 BMP colors_used欄位來損毀堆疊記憶體。攻擊者可以製作colors_used高於 256 的 BMP 或 ICO 文件，以溢出 768 位元組的顏色圖陣列，從而導致崩潰或潛在的程式碼執行。（CVE-2026-116723）

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。

  - FLTK through 1.4.5 在 Fl_BMP_Image：：load_bmp_（） 中包含基于堆栈的缓冲区溢出漏洞，允许攻击者通过提供超大的 BMP colors_used字段来损坏堆栈内存。攻击者可构建colors_used高于 256 的 BMP 或 ICO 文件来溢出 768 字节的颜色映射数组，从而造成崩溃或可能的代码执行。（CVE-2026-116723）

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

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。

  - 1.4.5 までのFLTKには、Fl_BMP_Image::load_bmp_()にスタックベースのバッファオーバーフローの脆弱性が含まれており、攻撃者が大きすぎるBMP colors_usedフィールドを提供することでスタックメモリを破損する可能性があります。攻撃者が 256 を超えるcolors_usedで BMP または ICO ファイルを細工し、768 バイトのカラーマップ配列をオーバーフローさせ、クラッシュを引き起こしたり、コードを実行する可能性があります。(CVE-2026-116723)

Nessus は、ベンダーから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。

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

  - FLTK through 1.4.5 contains a stack-based buffer overflow vulnerability in Fl_BMP_Image::load_bmp_() that     allows attackers to corrupt stack memory by supplying an oversized BMP colors_used field. Attackers can     craft BMP or ICO files with colors_used above 256 to overflow the 768-byte colormap array, causing crashes     or potential code execution. (CVE-2026-116723)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3459 advisory.

Attackers can     craft BMP or ICO files with colors_used above 256 to overflow the 768-byte colormap array, causing crashes     or potential code execution. (CVE-2026-116723)

    FLTK through 1.4.5 contains an integer overflow vulnerability in Fl_BMP_Image::load_bmp_() that causes     undersized pixel buffer allocation from file-supplied width and height. Attackers can supply a crafted BMP     or ICO file with large dimensions so row decoding writes file-derived data past the heap buffer,     corrupting the application heap. (CVE-2026-116724)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of fltk installed on the remote host is prior to 1.3.4-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-4115 advisory.
