USN-4685-1: OpenJPEG vulnerabilities

07 January 2021

Several security issues were fixed in OpenJPEG.



  • openjpeg2 - JPEG 2000 image compression/decompression library


It was discovered that OpenJPEG incorrectly handled certain image data. An
attacker could use this issue to cause OpenJPEG to crash, leading to a
denial of service, or possibly execute arbitrary code.

Update instructions

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

Ubuntu 20.10
Ubuntu 20.04

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