SB2013102503 - Gentoo update for GNU Automake

Description

This security bulletin contains information about 2 secuirty vulnerabilities.

1) Race condition (CVE-ID: CVE-2009-4029)

The vulnerability allows a local non-authenticated attacker to read and manipulate data.

The (1) dist or (2) distcheck rules in GNU Automake 1.11.1, 1.10.3, and release branches branch-1-4 through branch-1-9, when producing a distribution tarball for a package that uses Automake, assign insecure permissions (777) to directories in the build tree, which introduces a race condition that allows local users to modify the contents of package files, introduce Trojan horse programs, or conduct other attacks before the build is complete.

2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-3386)

The vulnerability allows a local non-authenticated attacker to read and manipulate data.

The "make distcheck" rule in GNU Automake before 1.11.6 and 1.12.x before 1.12.2 grants world-writable permissions to the extraction directory, which introduces a race condition that allows local users to execute arbitrary code via unspecified vectors.
