Description
This security bulletin contains information about 2 vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2026-42216)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to disclose sensitive information or cause a denial of service.
The vulnerability exists due to out-of-bounds read in IDManifest::init() in src/lib/OpenEXR/ImfIDManifest.cpp when parsing a prefix-compressed IDManifest string list from a crafted .exr file. A remote attacker can supply a specially crafted file to disclose sensitive information or cause a denial of service.
Exploitation requires the previous string to be longer than 255 bytes so that the 2-byte prefix-length path is used, and the next string to be empty.
2) Integer overflow (CVE-ID: CVE-2026-41142)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to integer overflow in ImageChannel::resize in OpenEXRUtil when parsing a crafted EXR image or using the public API with a crafted dataWindow. A remote attacker can supply crafted image dimensions that cause an undersized heap allocation and subsequent out-of-bounds write to execute arbitrary code.
User interaction is required to open or process a crafted EXR image.
