Name of the Vulnerable Software and Affected Versions radare2 versions prior to 6.1.4

Description A command injection issue exists in the PDB parser's print gvars() function. An attacker can execute arbitrary commands by embedding a newline byte in the PE section header name field. This is achieved by crafting a malicious PDB file with specific section names that inject r2 commands, which are then executed when the idp command processes the file.

Recommendations Update to version 6.1.4 or later. As a temporary workaround, avoid using the idp command to process untrusted PDB files.
