http://security.gentoo.org/

Severity:	normal
Title:	Apache Ant: Insecure temporary file
Date:	11/16/2020
Bugs:	#745768
ID:	202011-18

Synopsis

Apache Ant uses various insecure temporary files possibly allowing local code execution.

Background

Ant is a Java-based build tool similar to ‘make’ that uses XML configuration files.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-java/ant	< 1.10.9	>= 1.10.9	All supported architectures

Description

A previous fix for a security vulnerability involving insecure temporary files has been found to be incomplete.

Impact

A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All Apache Ant users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-java/ant-1.10.9"
