Description:
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.
Ubuntu-Description:
Notes:
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.
