Short explanation

A vulnerability exists in radare2 that allows remote code execution when loading crafted Pebble or Sega Mega Drive binary files.

Why does it matter?

This vulnerability allows attackers to execute commands with the privileges of the radare2 process, posing a severe security risk.

What should be done?

  • Update to version 6.2.2 or later.
  • Follow vendor advisories.
Chain of evidence and sources2 verified claims

radare2, 6.2.2 öncesi sürümlerde özel ikili dosyalar yüklenirken uzaktan kod çalıştırma açığı barındırmaktadır.

Show the technical text from the sources

radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.2, attacker-controlled data from several binary format plugins could reach RBinInfo->bclass. Opening or analyzing a crafted Pebble or Sega Mega Drive binary could place a dbg:// URI in bclass, causing radare2 to reopen the input through the debug input/output plugin and ultimately pass attacker-controlled arguments to execvp(). This could execute commands with the privileges of the radare2 process without an explicit debugging command. This issue is fixed in version 6.2.2.
