 -------------------------------------------------------------------------

 Package : libmatio Version : 1.5.19-2+deb11u1 CVE ID : CVE-2022-1515 CVE-2025-2338 CVE-2025-50343 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.
