Hello Kurt, Steve, vendors,

multiple integer overflows, leading to stack-based buffer overflows
were found in various stdlib functions of GNU libc (strtod, strtof,
strtold, strtod_l and related routines). If an application, using
the affected stdlib functions, did not perform user-level
sanitization of provided inputs, a local attacker could use this
flaw to cause such an application to crash or, potentially, execute
arbitrary code with the privileges of the user running the
application.
