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 <=3D 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
