libheif vulnerability
==========================================================================

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

- Ubuntu 24.04 LTS

Summary:

libheif could be made to crash or read sensitive data if it opened a
specially crafted file

Software Description:
- libheif: an ISO/IEC 23008-12:2017 HEIF and AVIF file format decoder and 
encoder

Details:

Gerrard Tai discovered that libheif did not properly validate certain
images, leading to out-of-bounds read and write vulnerability. If a user
or automated system were tricked into opening a specially crafted file, an
attacker could possibly use this issue to cause a denial of service or to
obtain sensitive information.

Update instructions:

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

Ubuntu 24.04 LTS
   libheif1                        1.17.6-1ubuntu4.1
