CVE-2025-59729 (CNNVD-202510-828)
中文标题:
FFmpeg 安全漏洞
英文标题:
Heap-buffer-overflow read in FFmpeg DHAV get_duration
漏洞描述
中文描述:
ffmpeg是meh.个人开发者的一个rust库。 FFmpeg 8.0之前版本存在安全漏洞，该漏洞源于解析DHAV文件头时整数下溢，可能导致读取分配缓冲区前的持续时间。
英文描述:
When parsing the header for a DHAV file, there's an integer underflow in offset calculation that leads to reading the duration from before the start of the allocated buffer. If we load a DHAV file that is larger than MAX_DURATION_BUFFER_SIZE bytes (0x100000) for example 0x101000 bytes, then at [0] we have size = 0x101000. At [1] we have end_buffer_size = 0x100000, and at [2] we have end_buffer_pos = 0x1000. The loop then scans backwards through the buffer looking for the dhav tag; when it is found, we'll calculate end_pos based on a 32-bit offset read from the buffer. There is subsequently a check [3] that end_pos is within the section of the file that has been copied into end_buffer, but it only correctly handles the cases where end_pos is before the start of the file or after the section copied into end_buffer, and not the case where end_pos is within the the file, but before the section copied into end_buffer. If we provide such an offset, (end_pos - end_buffer_pos) can underflow, resulting in the subsequent access at [4] occurring before the beginning of the allocation. We recommend upgrading to version 8.0 or beyond.
