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

  - Pillow is a Python imaging library. From 2.0.0 until 13.0.0, Pillow has a heap buffer overflow and stale-
    heap disclosure in _tiffWriteProc when saving compressed TIFF data through libtiff to a target without a
    usable fileno(), such as BytesIO. The callback sizes its allocation from the prior buffer size instead of
    the current write position, allowing an attacker-controlled out-of-line TIFF tag or retained ICC profile
    to be copied beyond the allocation after libtiff seeks forward. This overflow can crash the process and
    may allow code execution. Independently, unwritten alignment gaps in compressed TIFF output larger than 64
    KiB can disclose stale heap bytes without a crafted tag. File paths and targets with real file descriptors
    are unaffected. This issue is fixed in version 13.0.0. (CVE-2026-112393)

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

  - Pillow 是一個 Python 映像庫。從 2.0.0 直到 13.0.0，當透過 libtiff 將壓縮的 TIFF 資料儲存到沒有可用 fileno（） 的目標（例如 BytesIO）時，Pillow 在_tiffWriteProc中存在堆積緩衝區溢位和過時堆積洩漏。回呼會從先前的緩衝區大小 （而不是目前的寫入位置） 調整其配置大小，允許在 libtiff 向前搜尋之後，將攻擊者控制的行外 TIFF 標籤或保留的 ICC 設定檔複製到配置之外。此溢位可能會使進程崩潰，並可能允許程式碼執行。獨立地，壓縮 TIFF 輸出中大於 64 KiB 的未寫入對齊間隙可能會在沒有特製標籤的情況下洩露過時的堆積位元組。具有實際檔案描述元的檔案路徑和目標不受影響。13.0.0 版已修正此問題。(CVE-2026-112393)

請注意，Nessus 依賴供應商報告的套件存在。

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。

  - Pillow 是 Python 图像库。From 2.0.013.0.0until ， 将压缩的 TIFF 数据通过 libtiff 保存到没有可用 fileno（） 的目标（例如 BytesIO）时，Pillow 在 _tiffWriteProc 中存在堆缓冲区溢出和过时堆泄露。该回调从之前的缓冲区大小（而不是当前写入位置）调整其分配大小，从而允许攻击者控制的行外 TIFF 标签或保留的 ICC 配置文件在 libtiff 向前寻找后，复制到分配之外。此溢出可造成进程崩溃并可能允许代码执行。独立地，大于 64 KiB 的压缩 TIFF 输出中的未写入对齐间隙可在没有构建标签的情况下泄露过时的堆字节。具有实际文件描述符的文件路径和目标不受影响。此问题已在 13.0.0 版本中修复。(CVE-2026-112393)

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。

  - Pillow は Python イメージングライブラリです。2.0.0から13.0.0まで、Pillowでは、圧縮されたTIFFデータをBytesIOなどの使用可能なfileno()のないターゲットにlibtiffを介して保存するとき、_tiffWriteProcにヒープバッファオーバーフローと古いヒープ漏えいが発生します。コールバックは、現在の書き込み位置ではなく、以前のバッファサイズから割り当てサイズを変更するため、攻撃者がコントロールするアウトオブライン TIFF タグまたは保持された ICC プロファイルが、libtiff が前面にシークした後に、割り当てを超えてコピーされる可能性があります。このオーバーフローにより、プロセスがクラッシュしたり、コードが実行されたりする可能性があります。個別に、64 KiB を超える圧縮 TIFF 出力の不書き込みのアライメントギャップにより、細工されたタグなしで古いヒープバイトが漏洩する可能性があります。ファイルパスおよび実際のファイル記述子を持つターゲットは影響を受けません。この問題はバージョン 13.0.0 で修正されています。(CVE-2026-112393)

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。

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:1206 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2026-112405:
    A flaw was found in Pillow. A remote attacker can cause a Denial of Service (DoS) by supplying a specially     crafted image file to an application that processes images with the library. This issue occurs because the     Image.merge() function fails to properly validate the first input band, allowing mismatched image storage     formats to trigger a null pointer dereference. Consequently, processing the malformed image causes the     native application process to crash.

    CVE-2026-112398:
    Pillow is a Python imaging library. Prior to 13.0.0, Pillow's FlashPix JPEG-tile decoder can write decoded     scanlines beyond the allocated tile buffer. FlashPix (FPX) JPEG decoding selects raw mode LA with two     bytes per pixel, while an unrecognized JPEG mode can be decoded as JCS_UNKNOWN with four components,     causing ImagingJpegDecode to write four-component scanlines into the two-byte tile buffer. An attacker can     supply a crafted OLE2 FlashPix file to an application with the optional olefile dependency installed that     opens or thumbnails untrusted input. This can corrupt heap memory and may allow arbitrary code execution.
    This issue is fixed in version 13.0.0.

    CVE-2026-112393:
    Pillow is a Python imaging library. From 2.0.0 until 13.0.0, Pillow has a heap buffer overflow and stale-     heap disclosure in _tiffWriteProc when saving compressed TIFF data through libtiff to a target without a     usable fileno(), such as BytesIO. The callback sizes its allocation from the prior buffer size instead of     the current write position, allowing an attacker-controlled out-of-line TIFF tag or retained ICC profile     to be copied beyond the allocation after libtiff seeks forward. This overflow can crash the process and     may allow code execution. Independently, unwritten alignment gaps in compressed TIFF output larger than 64     KiB can disclose stale heap bytes without a crafted tag. File paths and targets with real file descriptors     are unaffected. This issue is fixed in version 13.0.0.

Tenable has extracted the preceding description block directly from the Tencent 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.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the b9a3fd21-d2af-11f1-bae2-3497f65b111b advisory.

    The Pillow project published security advisories for issues fixed               in release 13.0.0.  They include an argument injection in the               Ghostscript call used for EPS images, heap buffer overflows in               several image decoders that can lead to code execution, and               infinite loops and unbounded memory use when opening crafted               image files.
