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

Background
==========
Ant is a Java-based build tool similar to =E2=80=98make=E2=80=99 that uses =XML
configuration files.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-java/ant < 1.10.9 >= 1.10.9

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"
