CVE-2008-1687
The (1) maketemp and (2) mkstemp builtin functions in GNU m4 before 1.4.11 do not quote their output when a file is created, which might allow context-dependent attackers to trigger a macro expansion, leading to unspecified use of an incorrect filename.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.45%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
