Overview<\/strong><\/p>\n

This report discusses CVE-2025-57615, a severe vulnerability discovered in rust-ffmpeg 0.3.0. This security flaw affects rust-ffmpeg users and developers, posing significant risks due to the potential for system compromise or data leakage. The severity of this vulnerability underscores the importance of prompt and effective mitigation.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-57615
\nSeverity: High (7.5 CVSS)
\nAttack Vector: Remote
\nPrivileges Required: None
\nUser Interaction: No
\nImpact: Potential system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

rust-ffmpeg | 0.3.0 after commit 5ac0527<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The CVE-2025-57615 exploit takes advantage of an unchecked cast of a usize parameter to c_int in the Vector::new constructor function of rust-ffmpeg 0.3.0. 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

Conceptual Example Code<\/strong><\/p>\n

The following pseudocode demonstrates the concept of this vulnerability:<\/p>\n

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
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":"
