Doc Text:
A flaw was found in OpenJPEG. An out-of-bounds read and write vulnerability exists in the encoder's discrete wavelet transform processing when handling images with specific tile geometries. An attacker who can supply crafted encoding parameters could exploit this flaw to cause heap memory corruption, resulting in an application crash and a Denial of Service (DoS).

Description OSIDB Bzimport 2026-10-26 15:54:55 UTC
OpenJPEG 2.4.0 through 2.5.4, and git master through commit 8314119b, contains an out-of-bounds read and write in opj_dwt_encode_and_deinterleave_v() in src/lib/openjp2/dwt.c. This allows an attacker to cause a denial of service.
