The Config::IniFiles module before 2.71 for Perl creates temporary files
with predictable names, which allows local users to overwrite arbitrary
files via a symlink attack. NOTE: some of these details are obtained from
third party information. NOTE: it has been reported that this might only
be exploitable by writing in the same directory as the .ini file. If this
is the case, then this issue might not cross privilege boundaries.

Notes

Author	Note
jdstrand	file is created in the same directory as the original file and so yama won’t protect against it since this doesn’t have to occur in a sticky directory. Typically would not cross privilege boundaries, but is a useful hardening measure in all cases.
