{"apiVersion":"1.0","identifier":"CVE-2026-68513","description":"OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. Versions 3.3.0 through 3.3.12 and 3.4.0 through 3.4.13 contain a heap buffer overflow in PyOpenEXR triggered by a channel-name key collision between literal and prefixed RGB channels. When separate_channels=false, PyOpenEXR maps each physical channel name through channelNameToRGBA() and coalesces the results into a shared RGB array. A crafted flat scanline EXR that contains both a literal channel such as left and prefixed channels such as left.R, left.G, and left.B causes these names to collide, so the wrapper reuses an undersized two-dimensional NumPy array for the coalesced RGB slices and writes out of bounds when OpenEXR.File(path) decodes the pixels. This issue is fixed in versions 3.3.13 and 3.4.14.","publishedAt":"2026-08-25T20:17:02","lastModifiedAt":"2026-08-25T20:17:02","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-68513","cvssScore":7.1,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","epssProbability":0.00188,"riskScore":0.72,"affectedProduct":"OpenEXR","affectedVersions":">=3.3.0,<3.3.13, >=3.4.0,<3.4.14","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-68513","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-68513","en":"https://www.redsauce.net/en/cves/CVE-2026-68513","fr":"https://www.redsauce.net/fr/cves/CVE-2026-68513","pt":"https://www.redsauce.net/pt/cves/CVE-2026-68513","de":"https://www.redsauce.net/de/cves/CVE-2026-68513","sk":"https://www.redsauce.net/sk/cves/CVE-2026-68513","el":"https://www.redsauce.net/el/cves/CVE-2026-68513"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-68513"}}
