CVSS: 4.8EPSS: 0%CPEs: 1EXPL: 2CVE-2023-4039 – GCC's-fstack-protector fails to guard dynamically-sized local variables on AArch64
https://notcve.org/view.php?id=CVE-2023-4039
**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 to terminate your application, resulting in controlled loss of availability. An attacker who can exploit a buffer overflow without triggering the stack-protector might be able to change program flow control to cause an uncontrolled loss of availability or to go further and affect confidentiality or integrity. NOTE: The GCC project argues that this is a missed hardening bug and not a vulnerability by itself. • https://developer.arm.com/Arm%20Security%20Center/GCC%20Stack%20Protector%20Vulnerability%20AArch64 https://github.com/metaredteam/external-disclosures/security/advisories/GHSA-x7ch-h5rf-w2mf • 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
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 __builtin_darn intrínsecas en una sola llamada, reduciendo así la entropía del generador de números aleatorios. Esto ocurrió porque no se especificó una operación volátil. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00056.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00057.html http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00058.html https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91481 https://access.redhat.com/security/cve/CVE-2019-15847 https://bugzilla.redhat.com/show_bug.cgi?id=1755523 • CWE-331: Insufficient Entropy •

The std::random_device class in libstdc++ in the GNU Compiler Collection (aka GCC) before 4.9.4 does not properly handle short reads from blocking sources, which makes it easier for context-dependent attackers to predict the random values via unspecified vectors. La clase std::random_device en libstdc++ en el GNU Compiler Collection (también conocido como GCC) en versiones anteriores a 4.9.4 no maneja adecuadamente lecturas cortas desde fuentes bloqueadas, lo que hace mas fácil para atacantes dependientes del contexto predecir los valores aleatorios a través de vectores no especificados. • http://lists.opensuse.org/opensuse-updates/2015-11/msg00054.html http://lists.opensuse.org/opensuse-updates/2016-04/msg00052.html http://www.securitytracker.com/id/1034375 https://bugzilla.redhat.com/show_bug.cgi?id=1262846 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65142 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
