Arch Linux Security Advisory ASA-202106-27 ========================================== Severity: Medium Date : 2021-06-09 CVE-ID : CVE-2021-3578 Package : isync Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-2042 Summary ======= The package isync before version 1.4.2-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 1.4.2-1. # pacman -Syu "isync>=1.4.2-1" The problem has been fixed upstream in version 1.4.2. Workaround ========== None. Description =========== A security issue was found in mbsync before version 1.4.2, where an unchecked pointer cast allows a malicious or compromised server to write an arbitrary integer value past the end of a heap-allocated structure by issuing an unexpected APPENDUID response. This could be plausibly exploited for remote code execution on the client. Impact ====== A remote server could cause arbitrary code execution on the mbsync client using a crafted APPENDUID response.
