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

Description The issue is related to an out-of-bounds read in the src/lib/openjp2/pi.c component of the openjpeg library. This occurs when an attacker provides untrusted input to openjpeg's conversion or encoding functionality. The highest impact of this flaw is a disruption to application availability, potentially leading to 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 openjpeg's conversion and encoding functionality to trusted sources until a patch is applied.
