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

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

Description A flaw was found in openjpeg's src/lib/openjp2/t2.c, allowing an attacker to provide crafted input to openjpeg during conversion and encoding, causing an out-of-bounds write. The highest threat from this issue is to confidentiality, integrity, as well as system availability. This is due to insufficient input validation in the function.

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 use of the vulnerable t2.c function in src/lib/openjp2/ until a patch is available. Avoid using crafted input for conversion and encoding to minimize the risk of exploitation.
