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 lt;= 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.
Description
===========
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
