    Debian Bug     : 1100992 1104247 1124797

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

    CVE-2025-2337

      A vulnerability, which was classified as critical, has been found in
      libmatio Mat_VarPrint function. The manipulation leads to heap-based buffer
      overflow. The attack may be initiated remotely. The exploit has been
      disclosed to the public and may be used.

    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-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.

    For Debian 12 bookworm, these problems have been fixed in version
    1.5.23-2+deb12u1.

    For Debian 11 bullseye, see separate DLA-4459-1.

    We recommend that you upgrade your libmatio packages.
