Описание
OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions 3.1.0 through 3.2.10, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13, an int32_t multiplication in OpenEXRCore's unpack_sample_table() can overflow while decoding a crafted deep tiled EXR file, producing an invalid pointer that leads to a read from an unmapped memory address and a crash. Because the overflow occurs in the standard decoding path (exr_decoding_run), any application that decodes deep tiled EXR files is affected. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14.
A flaw was found in OpenEXR. An integer overflow vulnerability exists when decoding a specially crafted deep tiled EXR image file. This overflow can lead to an invalid memory pointer, causing applications that process these files to crash. This issue results in a denial of service.
Отчет
Red Hat has determined that versions of OpenEXR shipped in Red Hat Enterprise Linux 9, Red Hat Enterprise Linux 10, and Red Hat In-Vehicle OS 2 are within the affected version range (3.1.0 through 3.4.13). Red Hat Enterprise Linux 6, 7, and 8 ship OpenEXR versions prior to 3.1.0, where the vulnerable code was introduced, and are not affected. This flaw has been rated Moderate and is not currently planned to be addressed in future updates. For additional information, refer to the Mitigation section or the linked CVE page.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
