Name of the Vulnerable Software and Affected Versions vifm versions 0.12.1 through 0.14.3

Description A heap buffer overflow occurs during the history merge process when saving the state file (vifminfo.json). This is caused by a lack of runtime checks on the length of history entries in release builds, which may allow a crafted long path or command in the history to cause memory corruption or application crashes. A heap buffer overflow is a memory corruption issue that happens when a program writes more data to a heap-allocated memory block than it can hold.

Recommendations Update to the version containing commit 23063c7.
