A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage() in coders/svg.c. This issue is due to not checking the return value from libxml2's xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-017465 advisory.

    A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage()     in coders/svg.c. This issue is due to not checking the return value from libxml2's     xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue 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 NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage()     in coders/svg.c. This issue is due to not checking the return value from libxml2's     xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault.
    (CVE-2021-3596)

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

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage()
    in coders/svg.c. This issue is due to not checking the return value from libxml2's
    xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault.
    (CVE-2021-3596)

  - ImageMagick 7.1.0-27 is vulnerable to Buffer Overflow. (CVE-2022-28463)

  - A vulnerability was found in ImageMagick, causing an outside the range of representable values of type
    'unsigned char' at coders/psd.c, when crafted or untrusted input is processed. This leads to a negative
    impact to application availability or other problems related to undefined behavior. (CVE-2022-32545)

  - A vulnerability was found in ImageMagick, causing an outside the range of representable values of type
    'unsigned long' at coders/pcl.c, when crafted or untrusted input is processed. This leads to a negative
    impact to application availability or other problems related to undefined behavior. (CVE-2022-32546)

  - In ImageMagick, there is load of misaligned address for type 'double', which requires 8 byte alignment and
    for type 'float', which requires 4 byte alignment at MagickCore/property.c. Whenever crafted or untrusted
    input is processed by ImageMagick, this causes a negative impact to application availability or other
    problems related to undefined behavior. (CVE-2022-32547)

The version of ImageMagick installed on the remote host is prior to 6.9.10.97-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2253 advisory.

    A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage()     in coders/svg.c. This issue is due to not checking the return value from libxml2's     xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault.
    (CVE-2021-3596)

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

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

According to the versions of the ImageMagick packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage()     in coders/svg.c. This issue is due to not checking the return value from libxml2's     xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault.
    (CVE-2021-3596)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3007 advisory.

    CVE-2021-3596 A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in     ReadSVGImage() in coders/svg.c. This issue is due to not checking the return value from libxml2's     xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault.
    CVE-2022-28463 ImageMagick is vulnerable to Buffer Overflow. For Debian 9 stretch, these problems have     been fixed in version 8:6.9.7.4+dfsg-11+deb9u14. We recommend that you upgrade your imagemagick packages.
