Heap Buffer Overflow in vifm

vifm is vulnerable to a heap buffer overflow during the history merge process when saving the state file (vifminfo.json). This flaw occurs because the application lacks a runtime check on the length of history entries in release builds, potentially allowing a crafted long path or command in the history to cause memory corruption or application crashes. Releases from 0.12.1 to 0.14.3 (including) are considered vulnerable. This issue was fixed in commit 23063c7

Heap buffer overflow in Jansi

A heap buffer overflow vulnerability exists in the Jansi JNI "ioctl()" wrapper due to a lack of size verification for the argument array before the system call. This can lead to heap corruption and application crashes (DoS). All versions are believed to be vulnerable. This project is unmaintained at the time of CVE assignment.
