Public bug reported:
Binary package hint: dist
Fixes a grave issue which could cause data loss and to denial of service
as well
dist (1:3.5-17-2) unstable; urgency=high
* If a script uses a temp file which is created in /tmp, then an
attacker can create symlink with the same name in this directory in
order to destroy or rewrite some system or user files. Symlink attack
may also lead not only to the data desctruction but to denial of
service as well. Creating files with rand or pid to randomize the file
names is not adequate to protect the system. We now use File::Temp to
safely create the temporary files as needed. This closes a grave bug.
There are no code changes in this version, apart from the bug fix.
Closes: #496412
* Updated the Standards version. (No changes)
