According to Steve Grubb in Redhat #251774: It looks like coolkey creates /tmp/.pk11ipc1 as a world writable directory without the sticky bit. And...it creates the files under that potentially as world writable with the execute bit turned on or uses the file without any sanity check. coolkey runs as root sometimes and that makes it susceptible to doing symlink attacks. The only version in the tree is unstable at the moment, however.
seems that redhat issued a patch. crypto, please provide a fixed ebuild.
Added: coolkey-1.1.0-r1
thanks. closing without glsa.
