The remote host is missing an update for the 'libexif'
package(s) announced via the DLA-2222-1 advisory.

Vulnerability Insight:
Various minor vulnerabilities have been addredd in libexif, a library to
parse EXIF metadata files.


This issue had already been addressed via DLA-2214-1. However, upstream
provided an updated patch, so this has been followed up on.


Several buffer over-reads in EXIF MakerNote handling could have lead
to information disclosure and crashes. This issue is different from
already resolved CVE-2020-0093.


Use of uninitialized memory in EXIF Makernote handling could have
lead to crashes and potential use-after-free conditions.


An unrestricted size in handling Canon EXIF MakerNote data could have
lead to consumption of large amounts of compute time for decoding
EXIF data.

Affected Software/OS:
'libexif' package(s) on Debian Linux.

For Debian 8 'Jessie', these problems have been fixed in version

We recommend that you upgrade your libexif packages.
