AV:N/AC:M/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions openjpeg versions prior to 2.4.0

Description The issue is related to a flaw in openjpeg's t2 encoder, which can cause a null pointer dereference when crafted input is processed. This can lead to application availability issues. The flaw is associated with reading beyond the valid boundaries of a data buffer. An attacker who can provide specially designed input to be processed by openjpeg could exploit this issue, potentially causing a denial of service.

Recommendations For versions prior to 2.4.0, update to version 2.4.0 or later to resolve the issue. As a temporary workaround, consider restricting the input to the t2 encoder to prevent crafted input from being processed.
