Posted by TheSecguy on Oct 08 Hello, Short version: OpenJPEG has had a heap-buffer-overflow WRITE fixed on master since 2026-02-10 that has never appeared in a release. Every released version containing the affected code -- v2.5.3 and v2.5.4 -- is still vulnerable, and distributions are shipping it. There is no CVE and no advisory mapped to distro packages, so it is unlikely to be on packagers' radars.
OpenJPEG: heap-buffer-overflow write fixed on master since Feb 2026, still present in every release (2.5.3, 2.5.4)
