radareorg.radare2 is vulnerable to Use After Free
33
Low Risk
This Affects:
radareorg.radare2TL;DR
Affected versions of this package contain a use-after-free in r_core_seek_arch_bits in libr/core/disasm.c when switching architecture through the register profile handler. A freed structure is reused while seeking, leaving a dangling pointer that is dereferenced during disassembly. This can corrupt memory or crash radareorg.radare2. The patch reorders the profile update so the freed object is no longer accessed.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and run pde in a workflow that changes architecture or register profile during disassembly (for example via ahb).
Background info
radareorg.radare2 is vulnerable to Use After Free in versions 4.5.1 - 6.1.6.
How to fix this
Upgrade the radareorg.radare2 library to the patch version.
