USN-4987-1: ExifTool vulnerability

10 June 2021

libimage-exiftool-perl could be made to crash if it opened a specially crafted file.




It was discovered that ExifTool did not properly sanitize user data for the
DjVu file format. An attacker could use this vulnerability to cause a DoS or
possibly execute arbitrary code.

Update instructions

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

Ubuntu 21.04
Ubuntu 20.10
Ubuntu 20.04
Ubuntu 18.04

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