CyberRota Analysis
AI-GeneratedThe NE relocation fixup-chain parser in radare2 versions prior to 6.2.0 is vulnerable to a denial-of-service attack when processing crafted NE executables that create infinite loops in relocation entries. This flaw can lead to excessive CPU and memory consumption, potentially disrupting service availability. Users and organizations relying on radare2 for reverse engineering should prioritize upgrading to version 6.2.0 to mitigate this risk.

Original NVD Description
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.
