CVE-2017-11671

Priority
Low
Description
Under certain circumstances, the ix86_expand_builtin function in i386.c in
GNU Compiler Collection (GCC) version 4.6, 4.7, 4.8, 4.9, 5 before 5.5, and
6 before 6.4 will generate instruction sequences that clobber the status
flag of the RDRAND and RDSEED intrinsics before it can be read, potentially
causing failures of these instructions to go unreported. This could
potentially lead to less randomness in random number generation.
