Arch Linux Security Advisory ASA-202005-15 ========================================== Severity: Medium Date : 2020-05-20 CVE-ID : CVE-2020-1945 Package : ant Type : arbitrary command execution Remote : No Link : https://security.archlinux.org/AVG-1159 Summary ======= The package ant before version 1.10.8-1 is vulnerable to arbitrary command execution. Resolution ========== Upgrade to 1.10.8-1. # pacman -Syu "ant>=1.10.8-1" The problem has been fixed upstream in version 1.10.8. Workaround ========== None. Description =========== Apache Ant uses the default temporary directory identified by the Java system property java.io.tmpdir for several tasks and may thus leak sensitive information. The fixcrlf and replaceregexp tasks also copy files from the temporary directory back into the build tree allowing an attacker to inject modified source files into the build process. Impact ====== A local malicious user can inject code into the ant build process.
