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. Upstream bug report: [1] http://sourceware.org/bugzilla/show_bug.cgi?id=14459 Upstream patch (might not be the final one): [2] http://sourceware.org/ml/libc-alpha/2012-08/msg00202.html References: [3] https://bugzilla.redhat.com/show_bug.cgi?id=847715 Could you allocate a CVE id for this?
