This unchecked cast can lead to an integer overflow, resulting in a negative value being passed to the underlying C function sws_allocVec(). The result is a null pointer dereference that can cause a denial of service.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-946415666\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>The following pseudocode demonstrates the concept of this vulnerability:<\/p>\n<pre><code class=\"\" data-line=\"\">use rust_ffmpeg::Vector;\nfn main() {\n\/\/ Oversized usize value\nlet size: usize = usize::MAX;\n\/\/ Unchecked cast to c_int\nlet vec = Vector::new(size as c_int);\n\/\/ Call to vulnerable C function\nvec.sws_allocVec();\n}<\/code><\/pre>\n<p>This pseudocode does not represent an actual exploit but serves to illustrate the nature of the vulnerability. The oversized usize value triggers an integer overflow when cast to c_int, resulting in a negative value being passed to sws_allocVec() and leading to a null pointer dereference.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview This report discusses CVE-2025-57615, a severe vulnerability discovered in rust-ffmpeg 0.3.0.
