KEV Icon
CWE ID Description
CWE-190 The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

Executive Summary

libsndfile 1.2.2 has an integer overflow flaw in the mat4_read_header() function. This occurs when processing specially crafted MAT4 files, which are MATLAB v4 format audio files. The overflow can lead to memory corruption or crashes.

Detection Guidance

Detecting this vulnerability requires checking for the presence of libsndfile 1.2.2 or earlier versions on your system. Use commands like 'find / -name libsndfile.so*' or 'dpkg -l | grep libsndfile' to identify installed versions. Monitor network traffic for unusual MAT4 file processing activities.

Impact Analysis

If exploited, this vulnerability could allow an attacker to cause a denial of service by crashing the application or potentially execute arbitrary code. Users processing untrusted MAT4 files may be affected.

Mitigation Strategies

Immediately update libsndfile to version 1.2.3 or later. Disable or restrict processing of MAT4 files if not required. Apply network-level controls to block suspicious MAT4 file transfers. Monitor for exploitation attempts.
