In GraphicsMagick 1.4 snapshot-20181209 Q8, there is a heap-based buffer overflow in the WriteTGAImage function of tga.c, which allows attackers to cause a denial of service via a crafted image file, because the number of rows or columns can exceed the pixel-dimension restrictions of the TGA specification.

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5974-1 advisory.

  - In GraphicsMagick 1.4 snapshot-20181209 Q8, there is a heap-based buffer overflow in the WriteTGAImage     function of tga.c, which allows attackers to cause a denial of service via a crafted image file, because     the number of rows or columns can exceed the pixel-dimension restrictions of the TGA specification.
    (CVE-2018-20184)

  - In GraphicsMagick 1.3.31, the ReadDIBImage function of coders/dib.c has a vulnerability allowing a crash     and denial of service via a dib file that is crafted to appear with direct pixel values and also     colormapping (which is not available beyond 8-bits/sample), and therefore lacks indexes initialization.
    (CVE-2018-20189)

  - In GraphicsMagick 1.3.27, there is an infinite loop and application hang in the ReadBMPImage function     (coders/bmp.c). Remote attackers could leverage this vulnerability to cause a denial of service via an     image file with a crafted bit-field mask value. (CVE-2018-5685)

  - In GraphicsMagick 1.3.28, there is a divide-by-zero in the ReadMNGImage function of coders/png.c. Remote     attackers could leverage this vulnerability to cause a crash and denial of service via a crafted mng file.
    (CVE-2018-9018)

  - In GraphicsMagick 1.4 snapshot-20190322 Q8, there is a heap-based buffer over-read in the function     ReadMIFFImage of coders/miff.c, which allows attackers to cause a denial of service or information     disclosure via an RLE packet. (CVE-2019-11006)

  - GraphicsMagick through 1.3.35 has a heap-based buffer overflow in ReadMNGImage in coders/png.c.
    (CVE-2020-12672)

  - In GraphicsMagick, a heap buffer overflow was found when parsing MIFF. (CVE-2022-1270)

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

This update fixes several vulnerabilities in Graphicsmagick: Various memory handling problems and cases of missing or incomplete input sanitising may result in denial of service, memory disclosure or the execution of arbitrary code if malformed media files are processed.

It was discovered that GraphicsMagick incorrectly handled certain image files. An attacker could possibly use this issue to cause a denial of service or other unspecified impact.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu 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 :

Security vulnerabilities fixed :

  - CVE-2018-20184: Fixed heap-based buffer overflow in the     WriteTGAImage function of tga.c (bsc#1119822)

This update for GraphicsMagick fixes the following issues :

Security issues fixed :

  - CVE-2018-20184: Fixed heap-based buffer overflow in the     WriteTGAImage function of tga.c (bsc#1119822)

  - CVE-2018-20189: Fixed denial of service vulnerability in     ReadDIBImage function of coders/dib.c (bsc#1119790)

Multiple vulnerabilities have been found in GraphicsMagick, the image processing system.

CVE-2018-20184

The WriteTGAImage function (tga.c) is affected by a heap-based buffer overflow. Remote attackers might leverage this vulnerability to cause a denial of service via a crafted image file.

CVE-2018-20185

The ReadBMPImage function (bmp.c) is affected by a heap-based buffer over-read. Remote attackers might leverage this vulnerability to cause a denial of service via a crafted image file.

CVE-2018-20189

The ReadDIBImage function (coders/dib.c) is affected by an assertion error. Remote attackers might leverage this vulnerability to cause a denial of service via a crafted image file.

For Debian 8 'Jessie', these problems have been fixed in version 1.3.20-3+deb8u5.

We recommend that you upgrade your graphicsmagick packages.
