DESCRIPTION:
Some weaknesses have been reported in the GNU C Library, which can be
exploited by malicious people to cause a DoS (Denial of Service) or
potentially compromise an application using the library.

The weaknesses are caused due to integer overflow errors within the
"strtod()", "strtof()", "strtold()", and "strtod_l()" stdlib
functions when parsing input strings, which can be exploited to cause
buffer overflows via overly long strings passed to the functions.

The weaknesses are reported in version 2.16. Other versions may also
be affected.

SOLUTION:
No official solution is currently available.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
