CVE-2026-59183: CWE-190: Integer Overflow or Wraparound in AcademySoftwareFoundation openexr
CVE-2026-59183 is an integer overflow vulnerability in the AcademySoftwareFoundation openexr library affecting versions 3.1.0 through 3.2.10, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13. The flaw occurs in the unpack_sample_table() function during decoding of crafted deep tiled EXR files, leading to a crash due to a read from an unmapped memory address. This issue impacts any application decoding deep tiled EXR files. Fixed versions include 3.2.11, 3.3.13, and 3.4.14.
AI Analysis
Technical Summary
OpenEXR, a widely used image format implementation, contains an integer overflow in the unpack_sample_table() function within OpenEXRCore. The overflow arises from an int32_t multiplication when decoding crafted deep tiled EXR files, resulting in an invalid pointer and a subsequent crash due to reading unmapped memory. This vulnerability affects multiple version ranges: 3.1.0 to 3.2.10, 3.3.0 to 3.3.12, and 3.4.0 to 3.4.13. The issue is resolved in versions 3.2.11, 3.3.13, and 3.4.14.
Potential Impact
The vulnerability causes a denial of service (application crash) when processing maliciously crafted deep tiled EXR files. There is no impact on confidentiality or integrity reported. Exploitation requires local access with the ability to supply crafted EXR files. No known exploits in the wild have been reported.
Mitigation Recommendations
Users should upgrade to fixed versions 3.2.11, 3.3.13, or 3.4.14 of openexr to remediate this vulnerability. Patch status is not explicitly confirmed by a vendor advisory, but the description states these versions fix the issue. Until upgrading, avoid processing untrusted deep tiled EXR files to mitigate risk.
