CyberRota Analysis
AI-GeneratedThe Apple Preferred Executable Format loader in radare2 versions prior to 6.2.0 is vulnerable to a denial-of-service attack due to improper handling of relocation section counts in crafted PEF files, potentially leading to excessive CPU consumption. Users of radare2, particularly those utilizing it for reverse engineering tasks, should prioritize upgrading to version 6.2.0 to mitigate this risk. This vulnerability poses a medium severity threat, making it important for organizations relying on this tool to address it promptly.

Original NVD Description
radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's Apple Preferred Executable Format loader was vulnerable because the PEF loader accepted relocSecCount values that were not bounded by the number of sections or complete relocation records in the input. The vulnerability is triggered by normal binary-format auto-detection of a small crafted Apple PEF file. The loader could perform up to 268,435,456 relocation-section iterations and repeated buffer operations after record offsets passed the end of the file. This can cause denial of service through excessive CPU consumption and prolonged processing. This issue is fixed in version 6.2.0.
