    Version        : 1.5.19-2+deb11u1

    Debian Bug     : 1104247 1124797


    Multiple vulnerabilities has been discovered in libmatio, a MAT File I/O
    Library.

    CVE-2025-50343
      A Denial of Service (DoS) and in certain cases heap corruption vulnerability
      was found, which could lead to potential remote code execution if libmatio is
      embedded in services that accepts user-supplied .mat files.

    CVE-2025-2338
      A Denial of Service (DoS) and head-based buffer overflow was found, which
      could potentially lead to remote code execution if libmatio is embedded in
      services that accepts user-supplied .mat files.

    CVE-2022-1515
      A memory leak was discovered in matio 1.5.21 and earlier. This could lead
      to a potential Denial of Service (DoS).

    CVE-2020-36428
     A heap-based buffer overflow was found which could lead to potential remote
     code execution if libmatio is embedded in services that accepts user-supplied
     .mat files.

    Additionally CVE-2025-2337 and CVE-2020-36428 was investigated and deemed
    not to apply (directly) to this libmatio version.

    For Debian 11 bullseye, these problems have been fixed in version
    1.5.19-2+deb11u1.

    We recommend that you upgrade your libmatio packages.
