What is CVE-2025-59728?
CVE-2025-59728 is a high-severity memory corruption vulnerability in FFmpeg MPEG-DASH, published on 6 Oct 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
When calculating the content path in handling of MPEG-DASH manifests, there's an out-of-bounds NUL-byte write one byte past the end of the buffer.When we call xmlNodeGetContent below [0], it returns a buffer precisely allocated to match the string length, using strdup internally. If this buffer is not an empty string, it is assigned to root_url at [1].If the last (non-NUL) byte in this buffer is not '/' then we append '/' in-place at [2]. This will write two bytes into the buffer, starting at the last valid byte in the buffer, writing the NUL byte beyond the end of the allocated buffer. We recommend upgrading to version 8.0 or beyond.
Weakness: CWE-787
