==========================================================================

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

- Ubuntu 22.10
- Ubuntu 18.04 LTS
- Ubuntu 16.04 ESM
- Ubuntu 14.04 ESM

Summary:

Several security issues were fixed in ImageMagick.

Software Description:
- imagemagick: Image manipulation programs and library

Details:

It was discovered that ImageMagick incorrectly handled certain values
when processing PDF files. If a user or automated system using ImageMagick
were tricked into opening a specially crafted PDF file, an attacker could
exploit this to cause a denial of service. This issue only affected Ubuntu
14.04 ESM, Ubuntu 16.04 ESM and Ubuntu 18.04 LTS. (CVE-2021-20224)

Zhang Xiaohui discovered that ImageMagick incorrectly handled certain
values when processing image data. If a user or automated system using
ImageMagick were tricked into opening a specially crafted image, an
attacker could exploit this to cause a denial of service. This issue only
affected Ubuntu 18.04 LTS and Ubuntu 22.10. (CVE-2021-20241)

Zhang Xiaohui discovered that ImageMagick incorrectly handled certain
values when processing image data. If a user or automated system using
ImageMagick were tricked into opening a specially crafted image, an
attacker could exploit this to cause a denial of service. This issue only
affected Ubuntu 14.04 ESM, Ubuntu 18.04 LTS and Ubuntu 22.10.
(CVE-2021-20243)

It was discovered that ImageMagick incorrectly handled certain values
when processing visual effects based image files. By tricking a user into
opening a specially crafted image file, an attacker could crash the
application causing a denial of service. This issue only affected Ubuntu
22.10. (CVE-2021-20244)

It was discovered that ImageMagick could be made to divide by zero when
processing crafted file. By tricking a user into opening a specially
crafted image file, an attacker could crash the application causing a
denial of service. This issue only affected Ubuntu 22.10. (CVE-2021-20245)

It was discovered that ImageMagick incorrectly handled certain values
when performing resampling operations. By tricking a user into opening
a specially crafted image file, an attacker could crash the application
causing a denial of service. This issue only affected Ubuntu 22.10.
(CVE-2021-20246)

It was discovered that ImageMagick incorrectly handled certain values
when processing visual effects based image files. By tricking a user into
opening a specially crafted image file, an attacker could crash the
application causing a denial of service. This issue only affected Ubuntu
22.10. (CVE-2021-20309)

It was discovered that ImageMagick incorrectly handled certain values
when processing thumbnail image data. By tricking a user into opening
a specially crafted image file, an attacker could crash the application
causing a denial of service. This issue only affected Ubuntu 22.10.
(CVE-2021-20312)

It was discovered that ImageMagick incorrectly handled memory cleanup
when performing certain cryptographic operations. Under certain conditions
sensitive cryptographic information could be disclosed. This issue only
affected Ubuntu 22.10. (CVE-2021-20313)

It was discovered that ImageMagick did not properly manage memory under
certain circumstances. If a user were tricked into opening a specially
crafted file using convert command, an attacker could possibly use this
issue to cause ImageMagick to crash, resulting in a denial of service. This
issue only affected Ubuntu 22.10. (CVE-2021-3574)

It was discovered that ImageMagick did not use the correct rights when
specifically excluded by a module policy. An attacker could use this issue
to read and write certain restricted files. This issue only affected
Ubuntu 22.10. (CVE-2021-39212)

It was discovered that ImageMagick incorrectly handled certain values      
when processing specially crafted SVG files. By tricking a user into  
opening a specially crafted SVG file, an attacker could crash the        
application causing a denial of service. This issue only affected Ubuntu   
22.10. (CVE-2021-4219)

It was discovered that ImageMagick did not properly manage memory under    
certain circumstances. If a user were tricked into opening a specially     
crafted DICOM file, an attacker could possibly use this issue to cause
ImageMagick to crash, resulting in a denial of service or leaking sensitive
information. This issue only affected Ubuntu 22.10. (CVE-2022-1114)

It was discovered that ImageMagick incorrectly handled memory under
certain circumstances. If a user were tricked into opening a specially
crafted image file, an attacker could possibly exploit this issue to cause
a denial of service or other unspecified impact. This issue only affected
Ubuntu 22.10. (CVE-2022-28463)
