Arch Linux Security Advisory ASA-202001-2 ========================================= Severity: High Date : 2020-01-09 CVE-ID : CVE-2019-18218 Package : file Type : arbitrary code execution Remote : No Link : https://security.archlinux.org/AVG-1083 Summary ======= The package file before version 5.38-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 5.38-1. # pacman -Syu "file>=5.38-1" The problem has been fixed upstream in version 5.38. Workaround ========== None. Description =========== cdf_read_property_info in cdf.c in file through 5.37 does not restrict the number of CDF_VECTOR elements, which allows a heap-based buffer overflow (4-byte out-of-bounds write). Impact ====== An attacker is able to execute arbitrary code on the affected host by tricking a user to process a specially crafted file via libmagic or file.
