pacman prior to version 5.1.3 is affected by: Directory Traversal. The impact is: arbitrary file placement potentially leading to arbitrary root code execution. The component is: installing a remote package via a specified URL “pacman -U “. The problem was located in function curl_download_internal in lib/libalpm/dload.c line 535. The attack vector is: the victim must install a remote package via a specified URL from a malicious server (or a network MitM if downloading over HTTP). The fixed version is: 5.1.3 via commit 9702703633bec2c007730006de2aeec8587dfc84.
