GLSA 201310-17: pmake: Insecure temporary file usage

Severity:low
Title:pmake: Insecure temporary file usage
Date:10/28/2013
Bugs: #367891
ID:201310-17

Synopsis

pmake uses temporary files in an insecure manner, allowing for symlink attacks.

Background

pmake is Debian’s version of NetBSD’s make, a tool to build programs in parallel.

Affected packages

Package Vulnerable Unaffected Architecture(s)
sys-devel/pmake < 1.111.3.1 >= 1.111.3.1 All supported architectures

Description

/usr/share/mk/bsd.lib.mk and /usr/share/mk/bsd.prog.mk create temporary files insecurely, with predictable names (/tmp/_depend[PID]), and without using $TMPDIR.

Impact

The make include files allow local users to overwrite arbitrary files via a symlink attack.

Workaround

There is no known workaround at this time.

Resolution

All pmake users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=sys-devel/pmake-1.111.3.1"
