CVE-2023-2650 about OpenSSL on SFOS


Published 2023-05-30T14:15:00

Just reporting here for your acknowledgement

# An OpenSSL vulnerability has recently been fixed with USN-6188-1 & 6119-1:
# CVE-2023-2650: possible DoS translating ASN.1 object identifiers.
# Ensure you have updated the package to its latest version.

At the end of the vulnerability description:


The impact on TLS is relatively low, because all versions of OpenSSL have a 100KiB limit on the peer’s certificate chain. Additionally, this only impacts clients, or servers that have explicitly enabled client authentication. In OpenSSL 1.1.1 and 1.0.2, this only affects displaying diverse objects, such as X.509 certificates. This is assumed to not happen in such a way that it would cause a Denial of Service, so these versions are considered not affected by this issue in such a way that it would be cause for concern, and the severity is therefore considered low.

This means that only large-scale servers and clusters can be strongly affected by this vulnerability, and definitely this is not the case with smartphones.

However, in some other niches, this can be a sensitive problem, especially if it impacts the overall performance of the system, pushing it out of specifications about latency and jittering.

If this happens, the vulnerability is not the root cause, but having not provided real-time levels of running for those applications and kernel threads that require it.

At the moment this is the current state of SailFish OS:

Description :
The OpenSSL toolkit provides support for secure communications between
machines. OpenSSL includes a certificate management tool and shared
libraries which provide various cryptographic algorithms and

As you can see the package has been built three months before the CVE-2023-2650 publication therefore it is reasonable to suppose that the SFOS OpenSSL is still vulnerable.

I hope this helps, R-
