Описание
OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. Versions before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13 allow a crafted EXR with a nonzero dataWindow.min to make TypedFlatImageChannel::row() return an invalid heap pointer, causing out-of-bounds or use-after-free writes. This occurs when an application writes rows through FlatHalfChannel::row(). Affected consumers are tools, converters, render pipeline components, or image-processing services that accept untrusted EXR files and use FlatHalfChannel::row() on loaded images. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14.
A flaw was found in OpenEXR. A remote attacker could exploit this vulnerability by providing a specially crafted EXR image file with a nonzero dataWindow.min. This could cause the TypedFlatImageChannel::row() function to return an invalid memory pointer, leading to out-of-bounds or use-after-free writes when an application processes the image using FlatHalfChannel::row(). This could result in arbitrary code execution or a denial of service (DoS) in affected applications that process untrusted EXR files.
Меры по смягчению последствий
To mitigate this vulnerability, restrict the processing of EXR files to trusted sources only. Applications that use OpenEXR for writing image rows should avoid handling untrusted EXR files to prevent potential out-of-bounds write or use-after-free issues.
