What is CVE-2020-28045?

A vulnerability in ProlinOS allows an attacker to bypass security measures due to the lack of signature verification for shared libraries. While the operating system mandates that installed applications and system binaries are signed, shared libraries can be used without verification. This loophole enables an attacker to load a malicious shared object via the LD_PRELOAD mechanism, leading to the execution of unauthorized binaries within the system environment.
