FKIE_CVE-2025-62821
Vulnerability from fkie_nvd - Published: 2026-06-19 14:16 - Updated: 2026-10-12 22:10
Severity
Summary
Microsoft HEIF Image Extensions 1.2.22.0 has an out-of-bounds read because CHEIFItemInfoEntry_GetDataSize can return success while leaving the reported data size as 0. This causes a caller to make a 1-byte allocation. Later, CopyPixels computes copy_size = stride * abs(roi_height) but does not check the source buffer length before a memmove call.
