| Severity: | low |
| Title: | pmake: Insecure temporary file usage |
| Date: | 10/28/2013 |
| Bugs: | |
| 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"
