Stack Pointer Vulnerability in ARM mbed TLS Certificate Parsing

CVE-2017-2784

What is CVE-2017-2784?

A critical flaw exists in the x509 certificate parsing code of ARM's mbed TLS, allowing an attacker to manipulate the memory stack. When the library processes a specifically crafted x509 certificate, it risks an invalid stack pointer free, particularly enabling potential remote code execution. Attackers can exploit this by acting as either server or client, delivering malicious certificates to applications that utilize the affected mbed TLS versions. This vulnerability poses a significant security risk to systems relying on these versions of mbed TLS for secure communication.
