Several security issues were fixed in VIPS.

Releases

  o Ubuntu 22.04 LTS
  o Ubuntu 18.04 ESM
  o Ubuntu 16.04 ESM

Packages

  o vips - GObject introspection data for VIPS

Details

Ziqiang Gu discovered that VIPS could be made to dereference a NULL
pointer. If a user or automated system were tricked into processing
a specially crafted input image file, an attacker could possibly use
this issue to cause a denial of service. This issue only affected
Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. ( CVE-2018-7998 )

It was discovered that VIPS did not properly handle uninitialized memory
locations when processing corrupted input image data. An attacker could
possibly use this issue to generate output images that expose sensitive
information. This issue only affected Ubuntu 16.04 LTS
and Ubuntu 18.04 LTS. ( CVE-2019-6976 )

It was discovered that VIPS did not properly manage memory due to an
uninitialized variable. If a user or automated system were tricked into
processing a specially crafted output file, an attacker could possibly
use this issue to expose sensitive information.
This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.
( CVE-2020-20739 )

It was discovered that VIPS could be made to divide by zero in multiple
funcions. If a user or automated system were tricked into processing a
specially crafted image file, an attacker could possibly use this issue
to cause a denial of service. This issue only affected Ubuntu 16.04 LTS
and Ubuntu 18.04 LTS. ( CVE-2021-27847 )

It was discovered that VIPS did not properly handle certain input files
that contained malformed UTF-8 characters. If a user or automated system
were tricked into processing a specially crafted SVG image file, an
attacker could possibly use this issue to cause a denial of service.
This issue only affected Ubuntu 22.04 LTS. ( CVE-2023-40032 )
