Frequently Asked Questions
What must an attacker be able to do to exploit this issue?
The issue is a timing side channel in the RSA-PSK key exchange. Exploitation therefore concerns connections using RSA-PSK key exchange; the provided data does not identify any other prerequisite.
Which installed packages should be checked when assessing exposure?
Check for the listed GnuTLS packages, particularly libgnutls30 and gnutls. Development, debugging, HMAC, and debuginfo variants are also included in the update.
How can I determine whether the system has received the fix?
Verify that the security update SUSE-SU-2023:4983-1, published on 2023-12-28, has been applied to the affected GnuTLS packages. The provided data does not include fixed package version numbers.
