Ubuntu priority

Cvss 3 Severity Score

Description

In radare2 before version 4.5.0, malformed PDB file names in the PDB server path cause shell injection. To trigger the problem it's required to open the executable in radare2 and run idpd to trigger the download. The shell code will execute, and will create a file called pwned in the current directory.

Mitigation

Set up e bin.dbginfo=false in $HOME/.config/radare2/radare2rc to disable PDB autoloading and do not use idpd manually
