Vulnerability Title
OpenEXR: Heap out-of-bounds write in exrmultiview with subsampled channel union
Vulnerability Description
OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13, exrmultiview can write past a heap allocation when it combines two attacker-supplied, individually valid scanline EXR files whose union dataWindow is not aligned to one view's channel subsampling. The utility allocates sampled channel storage using a truncated union_width / xSampling, then reads the sampled input through a Slice based on the misaligned union window, producing a heap out-of-bounds write. The trigger is normal public-tool processing, such as exrmultiview left A.exr right B.exr out.exr with crafted but valid inputs, so this is not solely an API or caller-precondition issue. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14.

Academy Software Foundation OpenEXR 缓冲区错误漏洞
Vulnerability Description
Academy Software Foundation OpenEXR是美国Academy Software Foundation基金会开源的一种高动态范围图像(HDR)文件格式的开放标准。 Academy Software Foundation OpenEXR 3.2.11之前版本、3.3.0至3.3.12版本和3.4.0至3.4.13版本存在缓冲区错误漏洞,该漏洞源于exrmultiview工具在合并攻击者提供的EXR文件时,联合dataWindow未与视图的通道子采样对齐,导致堆越界写入,可能造成内
