m4 security advisore
The (1) maketemp and (2) mkstemp builtin functions in GNU m4 before 1.4.11 do not quote their output when a file is created, which might allow context-dependent attackers to trigger a macro expansion, leading to unspecified use of an incorrect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. Unspecified vulnerability in GNU m4 before 1.4.11 might allow context-dependent attackers to execute arbitrary code, related to improper handling of filenames specified with the -F option. NOTE: it is not clear when this issue crosses privilege boundaries.
