一、漏洞信息
漏洞编号：CVE-2023-4039
漏洞归属组件：gcc-7
漏洞归属的版本：7.3.0
CVSS V3.0分值：
BaseScore：4.8 Medium
Vector：CVSS：3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N
漏洞简述：
DISPUTEDA 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.
