High severity, CVSS 7.5. EPSS: 6.4% chance of exploitation in the next 30 days.

Multiple integer overflows in OpenEXR 1.2.2 and 1.6.1 allow context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via unspecified vectors that trigger heap-based buffer overflows, related to (1) the Imf::PreviewImage::PreviewImage function and (2) compressor constructors. NOTE: some of these details are obtained from third party information.
