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: 5.9EPSS: 0%CPEs: 23EXPL: 0CVE-2023-4813 – Glibc: potential use-after-free in gaih_inet()
https://notcve.org/view.php?id=CVE-2023-4813
A flaw was found in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge. Se encontró una falla en glibc. En una situación poco común, la función gaih_inet puede utilizar memoria que se ha liberado, lo que provoca un bloqueo de la aplicación. • http://www.openwall.com/lists/oss-security/2023/10/03/8 https://access.redhat.com/errata/RHSA-2023:5453 https://access.redhat.com/errata/RHSA-2023:5455 https://access.redhat.com/errata/RHSA-2023:7409 https://access.redhat.com/security/cve/CVE-2023-4813 https://bugzilla.redhat.com/show_bug.cgi?id=2237798 https://security.netapp.com/advisory/ntap-20231110-0003 • CWE-416: Use After Free •
