CVE-2021-37322 |
GCC c++filt v2.26 was discovered to contain a use-after-free vulnerability via the component cplus-dem.c. Published: November 18, 2021; 5:15:07 PM -0500 |
V4.0:(not available) V3.1: 7.8 HIGH V2.0: 6.8 MEDIUM |
CVE-2019-15847 |
The POWER9 backend in GNU Compiler Collection (GCC) before version 10 could optimize multiple calls of the __builtin_darn intrinsic into a single call, thus reducing the entropy of the random number generator. This occurred because a volatile operation was not specified. For example, within a single execution of a program, the output of every __builtin_darn() call may be the same.

V4.0:(not available) V3.1: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2018-12886 |
stack_protect_prologue in cfgexpand.c and stack_protect_epilogue in function.c in GNU Compiler Collection (GCC) 4.1 through 8 (under certain circumstances) generate instruction sequences when targeting ARM targets that spill the address of the stack protector guard, which allows an attacker to bypass the protection of -fstack-protector, -fstack-protector-all, -fstack-protector-strong, and -fstack-protector-explicit against stack overflow by controlling what the stack canary is compared against.

V4.0:(not available) V3.0: 8.1 HIGH V2.0: 6.8 MEDIUM |
CVE-2017-11671 |
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. Published: July 26, 2017; 5:29:00 PM -0400 |
V4.0:(not available) V3.0: 4.0 MEDIUM V2.0: 2.1 LOW |
