Summary
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.
Risk Assessment
This could lead to remote code execution with the privileges of the user running radare2, which is especially dangerous when analyzing untrusted files.
Recommendation
Update radare2 to version 6.2.2 or later.
Other vulnerabilities in radare2
See all- CVE-2026-8696High
Version 6.1.5 of radare2 contains a use-after-free vulnerability in the gdbr_pids_list() function, which can be exploited by remote attackers to cause a denial of service or potentially execute arbitrary code by sending malformed thread information responses.
- CVE-2026-8695High
radare2 version 6.1.5 contains a use-after-free vulnerability in the gdbr_threads_list() function. This allows remote attackers to trigger memory corruption by sending a valid qfThreadInfo response followed by a malformed qsThreadInfo response.
- CVE-2017-15932High
In radare2 version 2.0.1, an integer exception (negative number leading to an invalid memory access) exists in store_versioninfo_gnu_verdef() in elf.c, which can be triggered by crafted ELF files when parsing the ELF version on 32-bit systems.
- CVE-2017-15931High
In radare2 version 2.0.1, an integer exception (negative number leading to an invalid memory access) exists in store_versioninfo_gnu_verneed() in elf.c, which can be exploited via crafted ELF files on 32-bit systems.
- CVE-2017-15385High
The store_versioninfo_gnu_verdef function in radare2 2.0.0 allows remote attackers to cause a denial of service via a crafted ELF file, leading to an invalid write in r_read_le16 and application crash.
- CVE-2017-15368High
The wasm_dis function in radare2 version 2.0.0 allows remote attackers to cause denial of service through stack-based buffer over-read, leading to application crash. The attack can be executed using a crafted WASM file that triggers an incorrect r_hex_bin2str call.
- CVE-2017-10929High
The grub_memmove function in radare2 1.5.0 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) via a crafted binary file.
- CVE-2017-9949High
The grub_memmove function in radare2 1.5.0 allows remote attackers to cause a denial of service via a crafted binary file, potentially leading to application crashes due to a buffer underflow.
- CVE-2017-6448High
The dalvik_disassemble function in radare2 version 1.2.1 allows remote attackers to cause a denial of service (stack-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted DEX file.
- CVE-2017-6194High
The relocs function in libr/bin/p/bin_bflt.c in radare2 version 1.2.1 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted binary file.
