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。

  - 在 GIMP 中發現一個缺陷。PSD 縮圖資源載入器會以固定的 3 位元組步幅執行 BGR 到 RGB 的通道交換，並且不會驗證 JPEG 縮圖是否為 RGB。精心製作的灰階 PSD 縮圖可能會導致外掛程式進程中出現大量越界讀寫，從而導致受害者瀏覽或開啟檔案時崩潰並可能執行任意程式碼。（CVE-2026-112257）

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。

  - 在 GIMP 中发现一个缺陷。PSD 缩略图资源加载程序以固定的 3 字节步幅执行 BGR 到 RGB 通道交换，并且不验证 JPEG 缩略图是否为 RGB。特制的灰度 PSD 缩略图可在插件进程中造成堆栈越界读写，进而导致受害者浏览或打开文件时崩溃且可能执行任意代码。（CVE-2026-112257）

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。

  - GIMP に欠陥が見つかりました。PSD サムネイルリソースローダーは固定 3 バイトストライドで BGR から RGB へのチャネルスワップを実行し、JPEG サムネイルが RGB であることを検証しません。細工されたグレースケールの PSD サムネイルにより、プラグインプロセスでヒープの領域外読み取りおよび書き込みが引き起こされ、被害者がファイルを閲覧または開いたときにクラッシュしたり、任意のコードが実行されたりする可能性があります。(CVE-2026-112257)

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 remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:93975 advisory.

    The GIMP (GNU Image Manipulation Program) is an image composition and editing program. GIMP provides a     large image manipulation toolbox, including channel operations and layers, effects, sub-pixel imaging and     anti-aliasing, and conversions, all with multi-level undo.

    Security Fix(es):

    * gimp: GIMP: heap buffer overflow in DDS loader on crafted DirectDraw Surface file (CVE-2026-106062)

    * gimp: gimp: heap out-of-bounds read/write in PSD thumbnail loader (load_resource_1033) (CVE-2026-112257)

    * gimp: gimp: use-after-free in XCF loader via PROP_LINKED and PROP_SELECTION on channels     (CVE-2026-112258)

    * gimp: gimp: heap out-of-bounds read in XCF text-layer parasite parsing (CVE-2026-112260)

    * gimp: gimp: use-after-free in XCF loader via PROP_SELECTED_PATH (CVE-2026-112261)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in GIMP. The PSD thumbnail resource loader performs a BGR-to-RGB channel swap with a     fixed 3-byte stride and does not verify that the JPEG thumbnail is RGB. A crafted grayscale PSD thumbnail     can cause a heap out-of-bounds read and write in the plug-in process, leading to a crash and potentially     arbitrary code execution when the victim browses or opens the file. (CVE-2026-112257)

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

The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2026-93975 advisory.
