Technical Analysis
OpenEXR, a widely used image format library in the motion picture industry, contains an integer overflow vulnerability (CWE-190) in the unpack_sample_table() function within OpenEXRCore. Specifically, an int32_t multiplication can overflow while decoding a crafted deep tiled EXR file, resulting in an invalid pointer dereference and a crash. This affects any application decoding deep tiled EXR files using vulnerable versions. The vulnerability is addressed in versions 3.2.11, 3.3.13, and 3.4.14.
Potential Impact
The vulnerability leads to a denial of service (application crash) due to a read from an unmapped memory address. There is no indication of confidentiality or integrity impact. Exploitation requires user interaction (UI:R) and local access (AV:L).
Mitigation Recommendations
Upgrade OpenEXR to version 3.2.11, 3.3.13, or 3.4.14 or later, where this integer overflow vulnerability is fixed. No other mitigation is indicated.
