Date: August 14, 2012
Bug(s): #414485
ID: 201208-05

Synopsis

An insecure temporary file usage has been reported in the Perl
Config-IniFiles module, possibly allowing symlink attacks.


Background

Config-IniFiles is a Perl module for reading .ini-style configuration
files.


Affected Packages

Package: dev-perl/Config-IniFiles
Vulnerable: < 2.710.0
Unaffected: >= 2.710.0
Architectures: All supported architectures


Description

The Perl Config-IniFiles module uses predicatable temporary file names.

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 users of the Perl Config-IniFiles module should upgrade to the
latest version:
Code:
# emerge --sync
