Title

Rizin缓冲区溢出漏洞

Description

Rizin是Rizin组织的一个免费的开源逆向工程框架。用于分析二进制文件、反汇编代码、调试程序、作为取证工具、作为能够打开磁盘文件的可编写脚本的命令行十六进制编辑器等等。 Rizin 0.3.1及其之前版本存在缓冲区溢出漏洞，该漏洞源于当使用DWARF调试信息反转AMD64 ELF二进制文件时，在parse die()中会出现基于堆的出界写入。当受害用户打开恶意的AMD64 ELF二进制文件时，Rizin可能会崩溃或执行意外操作。目前没有详细的漏洞细节提供。

CVE-2021-43814 (GCVE-0-2021-43814)

Vulnerability from cvelistv5 – Published: 2021-12-13 19:35 – Updated: 2024-08-04 04:03

Title

Heap-based OOB write when parsing dwarf DIE info in Rizin

Summary

Rizin is a UNIX-like reverse engineering framework and command-line toolset. In versions up to and including 0.3.1 there is a heap-based out of bounds write in parse_die() when reversing an AMD64 ELF binary with DWARF debug info. When a malicious AMD64 ELF binary is opened by a victim user, Rizin may crash or execute unintended actions. No workaround are known and users are advised to upgrade.

Severity

7.7 (High)

Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
Not confirmed: The user expressed doubt about the validity of the vulnerability.
Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
