CVE-2026-8997
Description
A flaw was found in vifm, a file manager. This vulnerability, a heap buffer overflow, occurs when the application saves its state file (vifminfo.json) during the history merge process. A local user could exploit this by introducing a specially crafted, excessively long path or command into the history. This lack of proper length validation can lead to memory corruption, potentially causing the application to crash.
Statement

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.
