CVE-2020-1945

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.

Red Hat Lightwell has released org.apache.ant:ant 1.8.2.rhlw-00006 with backported fixes for CVE-2020-11979 and CVE-2020-1945.

CVE-2020-11979: As mitigation for CVE-2020-1945 Apache Ant 1.10.8 changed the permissions of temporary files it created so that only the current user was allowed to access them. Unfortunately the fixcrlf task deleted the temporary file and created a new one without said protection, effectively nullifying the effort. This would still allow an attacker to inject modified source files into the build process.

This patched artifact is a drop-in replacement for org.apache.ant:ant 1.8.2 from Maven Central.

Updated ant packages fix security vulnerability:

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 (CVE-2020-1945).

The ant package has been updated to version 1.10.8 to fix this issue and other bugs.

This update for ant fixes the following issues:

• CVE-2020-1945: Fixed an inseure temorary file vulnerability which could have potentially leaked sensitive information (bsc#1171696).

This update was imported from the SUSE:SLE-15-SP2:Update update project.

These are all security issues fixed in the ant-1.10.10-1.2 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the junit-4.13.2-1.1 package on the GA media of openSUSE Tumbleweed.

This update for ant fixes the following issues:

• CVE-2020-1945: Fixed an inseure temorary file vulnerability which could have potentially leaked sensitive information (bsc#1171696).

This update for ant fixes the following issues:

• CVE-2020-1945: Fixed insecure temporary file vulnerability (bsc#1171696).
• CVE-2020-11979: Fixed issue introduced with fix for CVE-2020-1945 (bsc#1177180).

It was discovered that Apache Ant created temporary files with insecure permissions. An attacker could use this vulnerability to read sensitive information leaked into /tmp, or potentially inject malicious code into a project that is built with Apache Ant.
