graphicsmagick vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 ESM
- Ubuntu 14.04 ESM

Summary:

Several security issues were fixed in GraphicsMagick.

Software Description:
- graphicsmagick: collection of image processing tools

Details:

It was discovered that GraphicsMagick was not properly performing bounds
checks when processing TGA image files, which could lead to a heap buffer
overflow. If a user or automated system were tricked into processing a
specially crafted TGA image file, an attacker could possibly use this
issue to cause a denial of service or execute arbitrary code. This issue
only affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. (CVE-2018-20184)

It was discovered that GraphicsMagick was not properly validating bits per
pixel data when processing DIB image files. If a user or automated system
were tricked into processing a specially crafted DIB image file, an
attacker could possibly use this issue to cause a denial of service. This
issue only affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM.
(CVE-2018-20189)

It was discovered that GraphicsMagick was not properly processing
bit-field mask values in BMP image files, which could result in the
execution of an infinite loop. If a user or automated system were tricked
into processing a specially crafted BMP image file, an attacker could
possibly use this issue to cause a denial of service. This issue only
affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. (CVE-2018-5685)

It was discovered that GraphicsMagick was not properly validating data
used in arithmetic operations when processing MNG image files, which
could result in a divide-by-zero error. If a user or automated system were
tricked into processing a specially crafted MNG image file, an attacker
could possibly use this issue to cause a denial of service. This issue
only affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. (CVE-2018-9018)

It was discovered that GraphicsMagick was not properly performing bounds
checks when processing MIFF image files, which could lead to a heap buffer
overflow. If a user or automated system were tricked into processing a
specially crafted MIFF image file, an attacker could possibly use this
issue to cause a denial of service or expose sensitive information. This
issue only affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM.
(CVE-2019-11006)

It was discovered that GraphicsMagick did not properly magnify certain
MNG image files, which could lead to a heap buffer overflow. If a user or
automated system were tricked into processing a specially crafted MNG
image file, an attacker could possibly use this issue to cause a denial
of service or execute arbitrary code. This issue only affected Ubuntu
20.04 LTS. (CVE-2020-12672)

It was discovered that GraphicsMagick was not properly performing bounds
checks when parsing certain MIFF image files, which could lead to a heap
buffer overflow. If a user or automated system were tricked into
processing a specially crafted MIFF image file, an attacker could possibly
use this issue to cause a denial of service or execute arbitrary code.
(CVE-2022-1270)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 20.04 LTS:
graphicsmagick 1.4+really1.3.35-1ubuntu0.1
libgraphicsmagick-q16-3 1.4+really1.3.35-1ubuntu0.1

Ubuntu 18.04 LTS:
graphicsmagick 1.3.28-2ubuntu0.2+esm1
libgraphicsmagick-q16-3 1.3.28-2ubuntu0.2+esm1

Ubuntu 16.04 ESM:
graphicsmagick 1.3.23-1ubuntu0.6+esm2
libgraphicsmagick-q16-3 1.3.23-1ubuntu0.6+esm2

Ubuntu 14.04 ESM:
graphicsmagick 1.3.18-1ubuntu3.1+esm8
libgraphicsmagick3 1.3.18-1ubuntu3.1+esm8

In general, a standard system update will make all the necessary changes.
