Prior to 6.2.0, radare2&#8217;s Mach-O Swift field-metadata parser was vulnerable because a relative Swift field pointer could be lower than the field-metadata section base, making subtraction produce a negative logical index. The vulnerability is triggered by parsing Swift type and class metadata from a crafted Mach-O file. The derived index was used to read four bytes immediately before the allocated field-metadata buffer. This can cause incorrect metadata processing or process termination; no attacker-observable memory disclosure has been demonstrated. This issue is fixed in version 6.2.0.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>radare2 is a UNIX-like reverse engineering framework and command-line toolset.
