| Vector | AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
OpenImageIO version 2.4.4.2
Description
The issue is related to a buffer overflow in the
close() function of the iffoutput component in the OpenImageIO library. This can be exploited by a remote attacker using a specially crafted file, potentially allowing access to confidential data, disrupting data integrity, and causing a denial of service. The vulnerability occurs when the ymax variable is set to 0xFFFF and m spec.format is TypeDesc::UINT8, leading to a heap buffer overflow.Recommendations
For OpenImageIO version 2.4.4.2, consider disabling the
close() function in the iffoutput component until a patch is available. Restrict access to the IFFOutput::close() functionality to minimize the risk of exploitation. Avoid using the ymax variable with a value of 0xFFFF and m spec.format set to TypeDesc::UINT8 in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
