Detailsinfo

A vulnerability, which was classified as critical, has been found in Oracle Communications Cloud Native Core Binding Support Function up to 23.1.7/23.2.2 (Cloud Software). This issue affects an unknown code of the component Install/Upgrade. Using CWE to declare the problem leads to CWE-693. The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product. Impacted is confidentiality, and integrity. The summary by CVE is:

**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.

The weakness was released 10/17/2023 as Oracle Critical Patch Update Advisory - October 2023. The advisory is shared at oracle.com. The identification of this vulnerability is CVE-2023-4039. Neither technical details nor an exploit are publicly available.
