Vulnerability Title
libde265 has a heap buffer overflow in de265_image_get_buffer via SPS dimension integer overflow
Vulnerability Description
libde265 is an open source implementation of the h.265 video codec. Prior to version 1.1.0, a crafted H.265 bitstream with large SPS dimensions and 16-bit bit depth causes a signed integer overflow in `de265_image_get_buffer()` (`libde265/image.cc:128`). The overflow wraps the plane allocation size to a small value (~1 KB), but the subsequent `fill_image()` call computes the real size using `size_t`, writing ~4 GB into the undersized heap buffer. Version 1.1.0 patches the issue.

Vulnerability Title
strukturag libde265 数字错误漏洞
Vulnerability Description
strukturag libde265是strukturag公司的一个处理HEVC视频编码的库。 strukturag libde265 1.1.0之前版本存在数字错误漏洞,该漏洞源于在`de265_image_get_buffer()`函数中,精心构造的H.265比特流会导致有符号整数溢出,分配大小被包装为小值,后续`fill_image()`调用写入约4GB数据到过小的堆缓冲区。
