GraphicsMagick before 1.3.35 has an integer overflow and resultant heap-based buffer overflow in HuffmanDecodeImage in magick/compress.c.

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5190-1 advisory.

    It was discovered that GraphicsMagick allowed reading arbitrary files via specially crafted images. An     attacker could use this issue to expose sensitive information. This issue only affects Ubuntu 14.04 ESM,     Ubuntu 16.04 ESM, and Ubuntu 18.04 ESM. (CVE-2019-12921)

    It was discovered that GraphicsMagick did not correctly handle memory allocations for error messages. An     attacker could use this issue to corrupt memory or possibly execute arbitrary code. This issue only     affects Ubuntu 14.04 ESM, Ubuntu 16.04 ESM, and Ubuntu 18.04 ESM. (CVE-2019-19950)

    It was discovered that GraphicsMagick did not correctly handle type limits. An attacker could use these     issues to cause heap-based buffer overflows, leading to a denial of service (application crash) or     possibly execute arbitrary code. These issues only affect Ubuntu 14.04 ESM, Ubuntu 16.04 ESM, and Ubuntu     18.04 ESM. (CVE-2019-19951, CVE-2019-19953)

    It was discovered that GraphicsMagick did not correctly handle the signed integer limit in 32-bit     applications. An attacker could use this issue to cause a heap-based buffer overflow, leading to a denial     of service (application crash) or possibly execute arbitrary code. This issue only affects Ubuntu 14.04     ESM, Ubuntu 16.04 ESM, and Ubuntu 18.04 ESM. (CVE-2020-10938)

    It was discovered that GraphicsMagick did not properly magnify certain images. An attacker could use this     issue to cause a heap-based buffer overflow, leading to a denial of service (application crash) or     possibly execute arbitrary code. (CVE-2020-12672)

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

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

Several vulnerabilities have been discovered in GraphicsMagick, a set of command-line applications to manipulate image files, which could result in information disclosure, denial of service or the execution of arbitrary code if malformed image files are processed.

A vulnerability was discovered in graphicsmagick, a collection of image processing tools, that results in a heap overflow in 32-bit applications because of a signed overflow on range check in the HuffmanDecodeImage function.

For Debian 8 'Jessie', this problem has been fixed in version 1.3.20-3+deb8u10.

We recommend that you upgrade your graphicsmagick packages.

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

This update for GraphicsMagick fixes the following issues :

  - CVE-2019-12921: Fixed an issue where text filename     components potentially coulf have allowed reading of     arbitrary files via TranslateTextEx (boo#1167208).

  - CVE-2020-10938: Fixed an integer overflow and resultant     heap-based buffer overflow in HuffmanDecodeImages     (boo#1167623).
