Detailsinfo

A vulnerability, which was classified as critical, was found in Oracle Communications Cloud Native Core Policy up to 23.1.8/23.2.4 (Cloud Software). Affected is an unknown code block of the component Install/Upgrade. CWE is classifying the issue as CWE-693. The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product. This is going to have an impact on confidentiality, and integrity. CVE summarizes:

**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 disclosed 10/17/2023 as Oracle Critical Patch Update Advisory - October 2023. The advisory is available at oracle.com. This vulnerability is traded as CVE-2023-4039. The technical details are unknown and an exploit is not available.
