https://notcve.org/view.php?id=CVE-2023-4039
13 Sep 2023 — **DISPUTED**A failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 allows an attacker to exploit an existing buffer overflow in dynamically-sized local variables in your application without this being detected. This stack-protector failure only applies to C99-style dynamically-sized local variables or those created using alloca(). The stack-protector operates as intended for statically-sized local variables. The default behavior when the stack-protector detects an overflow is... • https://developer.arm.com/Arm%20Security%20Center/GCC%20Stack%20Protector%20Vulnerability%20AArch64 • CWE-693: Protection Mechanism Failure •

CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 0CVE-2019-15847 – gcc: POWER9 "DARN" RNG intrinsic produces repeated output
https://notcve.org/view.php?id=CVE-2019-15847
02 Sep 2019 — 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. El backend POWER9 en GNU Compiler Collection (GCC) en versiones anteriores a la 10 podría optimizar múltiples llamadas de __buil... • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00056.html • CWE-331: Insufficient Entropy •

22 May 2019 — 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. stack_protec... • https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/config/arm/arm-protos.h?revision=266379&view=markup • CWE-209: Generation of Error Message Containing Sensitive Information •
