    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a heap information disclosure vulnerability exists in ImageMagick's PSD     (Adobe Photoshop) format handler. When processing a maliciously crafted PSD file containing ZIP-compressed     layer data that decompresses to less than the expected size, uninitialized heap memory is leaked into the     output image. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-24481)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, Magick fails to check for multi-layer nested mvg conversions to svg,     leading to DoS. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-24484)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, when a PCD file does not contain a valid Sync marker, the DecodeImage()     function becomes trapped in an infinite loop while searching for the Sync marker, causing the program to     become unresponsive and continuously consume CPU resources, ultimately leading to system resource     exhaustion and denial of service. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-24485)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a heap buffer over-read vulnerability exists in multiple raw image format     handles. The vulnerability occurs when processing images with -extract dimensions larger than -size     dimensions, causing out-of-bounds memory reads from a heap-allocated buffer. Versions 7.1.2-15 and     6.9.13-40 contain a patch. (CVE-2026-25576)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, memory leak exists in `coders/msl.c`. In the `WriteMSLImage` function of     the `msl.c` file, resources are allocated. But the function returns early without releasing these     allocated resources. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-25638)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, in `ReadSFWImage()` (`coders/sfw.c`), when temporary file creation fails,     `read_info` is destroyed before its `filename` member is accessed, causing a NULL pointer dereference and     crash. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-25795)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, in `ReadSTEGANOImage()` (`coders/stegano.c`), the `watermark` Image     object is not freed on three early-return paths, resulting in a definite memory leak (~13.5KB+ per     invocation) that can be exploited for denial of service. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
    (CVE-2026-25796)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, the ps coders, responsible for writing PostScript files, fails to     sanitize the input before writing it into the PostScript header.  An attacker can provide a malicous file     and inject arbitrary PostScript code. When the resulting file is processed by a printer or a viewer (like     Ghostscript), the injected code is interpreted and executed. The html encoder does not properly escape     strings that are written to in the html document. An attacker can provide a malicious file and injection     arbitrary html code. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-25797)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a NULL pointer dereference in ClonePixelCacheRepository allows a remote     attacker to crash any application linked against ImageMagick by supplying a crafted image file, resulting     in denial of service. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-25798)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a logic error in YUV sampling factor validation allows an invalid     sampling factor to bypass checks and trigger a division-by-zero during image loading, resulting in a     reliable denial-of-service. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-25799)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, the UIL and XPM image encoder do not validate the pixel index value     returned by `GetPixelIndex()` before using it as an array subscript. In HDRI builds, `Quantum` is a     floating-point type, so pixel index values can be negative. An attacker can craft an image with negative     pixel index values to trigger a global buffer overflow read during conversion, leading to information     disclosure or a process crash. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-25898)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, ImageMagick's path security policy is enforced on the raw filename string     before the filesystem resolves it. As a result, a policy rule such as /etc/* can be bypassed by a path     traversal. The OS resolves the traversal and opens the sensitive file, but the policy matcher only sees     the unnormalized path and therefore allows the read. This enables local file disclosure (LFI) even when     policy-secure.xml is applied. Actions to prevent reading from files have been taken in versions .7.1.2-15     and 6.9.13-40 But it make sure writing is also not possible the following should be added to one's policy.
    This will also be included in ImageMagick's more secure policies by default. (CVE-2026-25965)

    ImageMagick is free and open-source software used for editing and manipulating digital images. The shipped     secure security policy includes a rule intended to prevent reading/writing from standard streams.
    However, ImageMagick also supports fd:<n> pseudo-filenames (e.g., fd:0, fd:1). Prior to versions 7.1.2-15     and 6.9.13-40, this path form is not blocked by the secure policy templates, and therefore bypasses the     protection goal of no stdin/stdout. Versions 7.1.2-15 and 6.9.13-40 contain a patch by including a     change to the more secure policies by default. As a workaround, add the change to one's security policy     manually. (CVE-2026-25966)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a stack buffer overflow occurs when processing the an attribute in msl.c.
    A long value overflows a fixed-size stack buffer, leading to memory corruption. Versions 7.1.2-15 and     6.9.13-40 contain a patch. (CVE-2026-25968)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a signed integer overflow vulnerability in ImageMagick's SIXEL decoder     allows an attacker to trigger memory corruption and denial of service when processing a maliciously     crafted SIXEL image file. The vulnerability occurs during buffer reallocation operations where pointer     arithmetic using signed 32-bit integers overflows. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
    (CVE-2026-25970)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, Magick fails to check for circular references between two MSLs, leading     to a stack overflow. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-25971)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a heap out-of-bounds read vulnerability exists in the `coders/dcm.c`     module. When processing DICOM files with a specific configuration, the decoder loop incorrectly reads     bytes per iteration. This causes the function to read past the end of the allocated buffer, potentially     leading to a Denial of Service (crash) or Information Disclosure (leaking heap memory into the image).
    Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-25982)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a crafted MSL script triggers a heap-use-after-free. The operation     element handler replaces and frees the image while the parser continues reading from it, leading to a UAF     in ReadBlobString during further parsing. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
    (CVE-2026-25983)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a crafted SVG file containing an malicious element causes ImageMagick to     attempt to allocate ~674 GB of memory, leading to an out-of-memory abort. Versions 7.1.2-15 and 6.9.13-40     contain a patch. (CVE-2026-25985)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a heap buffer overflow write vulnerability exists in ReadYUVImage()     (coders/yuv.c) when processing malicious YUV 4:2:2 (NoInterlace) images. The pixel-pair loop writes one     pixel beyond the allocated row buffer. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-25986)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a heap buffer over-read vulnerability exists in the MAP image decoder     when processing crafted MAP files, potentially leading to crashes or unintended memory disclosure during     image decoding. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-25987)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, sometimes msl.c fails to update the stack index, so an image is stored in     the wrong slot and never freed on error, causing leaks. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
    (CVE-2026-25988)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a crafted SVG file can cause a denial of service. An off-by-one boundary     check (`>` instead of `>=`) that allows bypass the guard and reach an undefined `(size_t)` cast. Versions     7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-25989)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a crafted profile contain invalid IPTC data may cause an infinite loop     when writing it with `IPTCTEXT`. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-26066)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, a `continue` statement in the JPEG extent binary search loop in the jpeg     encoder causes an infinite loop when writing persistently fails. An attacker can trigger a 100% CPU     consumption and process hang (Denial of Service) with a crafted image. Versions 7.1.2-15 and 6.9.13-40     contain a patch. (CVE-2026-26283)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, ImageMagick lacks proper boundary checking when processing Huffman-coded     data from PCD (Photo CD) files. The decoder contains an function that has an incorrect initialization that     could cause an out of bounds read. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-26284)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, the MSL interpreter crashes when processing a invalid `<map>` element     that causes it to use an image after it has been freed. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
    (CVE-2026-26983)

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.

  - ImageMagick before 7.1.2-15 (and 6.x before 6.9.13-40) contains a heap out-of-bounds read in the PCD     coder's DecodeImage loop. A crafted PCD file can trigger a one-byte heap out-of-bounds read during image     decoding, resulting in denial of service and potential disclosure of an adjacent heap byte.
    (CVE-2026-56378)

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