CVE-2025-50343
Description
A flaw was found in matio. This vulnerability involves a memory error within the Mat_VarCreateStruct() function, where the system incorrectly handles the number of fields in a data structure. This can lead to out-of-bounds memory access and improper memory cleanup. An attacker could exploit this issue to cause the application to crash, resulting in a denial of service, or potentially to execute unauthorized code on the affected system.
Statement
This vulnerability is rated Moderate because it involves heap-based memory corruption, which could lead to a denial of service or other impacts. Exploitation requires user interaction, such as opening a specially crafted MAT file, limiting the attack vector.
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of a program's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the program into an infinite loop.
