Subject: Insecure usage of /tmp/.UUID_STATE
Download (untitled) / with headers
text/plain 306b
A symlink attack via Data::UUID seems to be possible. As user2: ln -s /home/user1/test-file /tmp/.UUID_STATE As user1: perl -MData::UUID -e 'Data::UUID->new' Then /home/user1/test-file is overwritten. I could not achieve the same result via /tmp/.UUID_NODEID, but I have not studied this carefully.
Reposted at https://github.com/rjbs/Data-UUID/issues/5 which is now the preferred bug tracker.
Thanks. As it's now there, I'm closing it here. -- rjbs
