Arch Linux Security Advisory ASA-202204-4
=========================================

Severity: Medium
Date    : 2022-04-04
CVE-ID  : CVE-2021-4022 CVE-2021-43814
Package : rizin
Type    : multiple issues
Remote  : No
Link    : https://security.archlinux.org/AVG-2590

Summary
=======

The package rizin before version 0.3.2-1 is vulnerable to multiple
issues including arbitrary code execution and denial of service.

Resolution
==========

Upgrade to 0.3.2-1.

# pacman -Syu "rizin>=0.3.2-1"

The problems have been fixed upstream in version 0.3.2.

Workaround
==========

None.

Description
===========

- CVE-2021-4022 (denial of service)

A specially crafted binary can make Rizin segfault when it tries to
analyze it (doing a full analysis with aaa). In
rz_core_analysis_type_match retctx structure was initialized on the
stack only after a "goto out_function", where a field of that structure
was freed. When the goto path is taken, the field is not properly
initialized and it could cause a crash of Rizin or have other effects.

- CVE-2021-43814 (arbitrary code execution)

In Rizin 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.

Impact
======

An attacker is able to provide a malicious AMD64 ELF binary that when
opened by a victim may execute arbitrary code on the affected host.
