CVE-2022-1240: Heap buffer overflow in libr/bin/format/mach0/mach0.c in radareorg/radare2
First published: Wed Apr 06 2022(Updated: )
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](https://cwe.mitre.org/data/definitions/122.html).
