CVE-2022-1240
Description
Heap buffer overflow in libr/bin/format/mach0/mach0.c in GitHub repository radareorg/radare2 prior to 5.8.6. If address sanitizer is disabled during the compiling, the program should executes into the r_str_ncpy function. Therefore I think it is very likely to be exploitable. For more general description of heap buffer overflow, see CWE.
