Insecure Binary compilation
Description
The binary for the IOS platform has been compiled without the Stack Smashing Protector (SSP) and Automatic Reference Counting (ARC) flags which provide protection against Stack Overflow attacks and memory corruption.
Impact
Overwrite registers in memory or cause a denial of service through buffer overflow attacks.
Recommendation
Compile binaries with ARC and fstack-protector-all flags.
Threat
Internal attacker with access to the IPA.
Expected Remediation Time
⌚ 450 minutes.

Compliant code
The application includes ARC and fstack-protector-all flags configured for binary file compilation
sample_app = executable('sample_app',
