https://security.gentoo.org/
Severity: Normal
Title: LMBench: Insecure temporary file usage
Date: September 09, 2009
Bugs: #246015
ID: 200909-10
Synopsis
=======
Multiple insecure temporary file usage issues have been reported in
LMBench, allowing for symlink attacks.
Background
=========
LMBench is a suite of simple, portable benchmarks for UNIX platforms.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-benchmarks/lmbench <= 3 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.
==========
Dmitry E. Oboukhov reported that the rccs and STUFF scripts do not
handle "/tmp/sdiff.#####" temporary files securely. NOTE: There might
be further occurances of insecure temporary file usage.
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
=========
LMBench has been removed from Portage. We recommend that users unmerge
LMBench:
# emerge --unmerge app-benchmarks/lmbench
