Dear arms,



I hope this message finds you well.


I am writing to inquire about the issue of ARM gcc5 CVE-2023-4039. According to the advisory on GitHub (https://github.com/metaredteam/external-disclosures/security/advisories/GHSA-x7ch-h5rf-w2mf), this bug affects versions from 5.4.0 to the trunk as of May 15, 2023.


However, I noticed that currently, patches are only provided for gcc7 and above, as per the information available on the ARM Security Center (https://developer.arm.com/Arm%20Security%20Center/GCC%20Stack%20Protector%20Vulnerability%20AArch64).


Given the potential impact of this vulnerability, I am particularly interested in a patch for gcc5. Could you please provide information on whether a patch for gcc5 is available or planned? If not, could you suggest any possible workarounds or mitigation strategies for systems that are currently using gcc5?


I appreciate your attention to this matter and look forward to your response.


Best regards,

This is the upstream gcc project's mailing list. If you want to ask ARM
about patches to their gcc builds, you should ask ARM.
