There is no fixed version for Debian:unstable radare2.
NVD Description
Note: Versions mentioned in the description apply only to the upstream radare2 package and not the radare2 package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's NE relocation fixup-chain parser was vulnerable because the NE relocation parser followed fixup chains without an active iteration limit or cycle detection. The vulnerability is triggered by opening a crafted NE executable whose in-bounds relocation entry points back to itself instead of reaching 0xffff. The parser repeatedly processed the same relocation and allocated another relocation object on each iteration. This can cause denial of service through continuous CPU and memory consumption. This issue is fixed in version 6.2.0.
