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.
