Title
radare2: Heap out-of-bounds read in radare2 Mach-O LC_DATA_IN_CODE parser
Summary
radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's Mach-O LC_DATA_IN_CODE parser was vulnerable because the Mach-O LC_DATA_IN_CODE parser trusted dataoff and datasize and allowed a final partial record to be processed. The vulnerability is triggered by opening a crafted Mach-O file while the non-default bin.verbose option is enabled. When datasize was not a multiple of data_in_code_entry, the last iteration read beyond the allocated buffer. This can cause a heap out-of-bounds read and possible process termination; no attacker-observable memory disclosure has been demonstrated. This issue is fixed in version 6.2.0.

The vulnerability is triggered by opening a crafted Mach-O file while the non-default bin.verbose option is enabled. When datasize was not a multiple of data_in_code_entry, the last iteration read beyond the allocated buffer. This can cause a heap out-of-bounds read and possible process termination; no attacker-observable memory disclosure has been demonstrated. This issue is fixed in version 6.2.0."
