Description

This security bulletin contains information about 1 vulnerability.


1) Heap-based buffer overflow (CVE-ID: CVE-2026-68515)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service or corrupt memory.

The vulnerability exists due to a heap-based buffer overflow in the exrmultiview utility when processing two attacker-supplied scanline EXR files whose combined data window is not aligned to a view's channel subsampling. A remote attacker can supply crafted EXR inputs to trigger a heap out-of-bounds write and cause a denial of service or corrupt memory.

User interaction is required to open or process the crafted EXR files.
