Out-of-bounds Write

CVE-2022-1240

High
7.8/10

Summary

Heap buffer overflow in "libr/bin/format/mach0/mach0.c" in radare2 prior to 5.6.8. If address sanitizer is disabled during the compiling, the program should execute into the "r_str_ncpy" function. Therefore I think it is very likely to be exploitable.
