Vulnerability details
The vulnerability allows a remote attacker to cause a denial of service by crashing radare2.
The vulnerability exists due to unchecked null pointers in the PDB TPI type-printing helpers in libr/bin/format/pdb/tpi.c when resolving referenced types and invoking their printing callbacks. A remote attacker can trick a victim into printing type records from a crafted PDB file containing an out-of-range type index to trigger a null pointer dereference and crash the process.
