Description
This security bulletin contains information about 3 vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2026-40244)
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 corrupt heap memory.
The vulnerability exists due to integer overflow in DWA setupChannelData planarUncRle pointer arithmetic when parsing a crafted EXR file. A remote attacker can supply a crafted DWAA/DWAB EXR file with large dimensions to corrupt heap memory.
User interaction is required to open the crafted file, and the issue is triggered on non-DCT channels, including UINT or single-channel layouts.
2) Integer overflow (CVE-ID: CVE-2026-40250)
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 corrupt the heap.
The vulnerability exists due to integer overflow or wraparound in DwaCompressor_uncompress() in internal_dwa_compressor.h when parsing a crafted DWAA/DWAB EXR file. A remote attacker can trick the victim into opening a crafted file to corrupt the heap.
User interaction is required to open a crafted file.
3) Integer overflow (CVE-ID: CVE-2026-34589)
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 or cause a denial of service.
The vulnerability exists due to integer overflow leading to an out-of-bounds write in the DWA lossy decoder when parsing a crafted scanline DWAA file. A remote attacker can supply a specially crafted file to execute arbitrary code or cause a denial of service.
User interaction is required to open or process the crafted file.
