Technical Analysis
CVE-2026-61555 is an out-of-bounds read vulnerability in the OpenEXR library, specifically triggered by the Imf::GetChannelsInMultiPartFile() function when it processes an EXR file containing an empty multiView header attribute. The Imf::viewFromChannelName() function then attempts to index an empty vector for a dotless channel name, causing a crash. This affects OpenEXR versions prior to 3.2.11, versions 3.3.0 through 3.3.12, and versions 3.4.0 through 3.4.13. The vulnerability has been addressed 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 specially crafted EXR files. There is no indication of confidentiality or integrity impact. The CVSS score is 5.5 (medium severity), reflecting the local attack vector, low complexity, no privileges required, user interaction required, and impact limited to availability.
Mitigation Recommendations
Upgrade OpenEXR to version 3.2.11, 3.3.13, or 3.4.14 or later to remediate this vulnerability. No other mitigation or workaround is indicated.
