Apache Ant 1.1 to 1.9.14 and 1.10.0 to 1.10.7 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.

msalvatore | There are two potential mitigations for this vulnerability. 1) Set your umask to 077. 2) Set your JVM’s java.io.tmpdir system property to a directory only readable and writable by the current user running Ant. The fix for this CVE is incomplete. CVE-2020-11979 finishes resolving the issue. |
