[Bug 2125752] Re: OpenSSL package in Ubuntu 24.04 needs updating

[Tobias Heider]

Looking only at the upstream version number is not enough to determine if the package is vulnerable. Fixes usually get backported individually without bumping to a newer upstream release.
Check out the changelog at https://git.launchpad.net/ubuntu/+source/openssl/tree/debian/changelog?h=ubuntu/noble-security and you will see that it includes a CVE fix for the issue you mentioned and a lot more.

If you want to verify whether a specific CVE was fixed in our packages
you can also take a look at

Title:
  OpenSSL package in Ubuntu 24.04 needs updating

Status in openssl package in Ubuntu:
  New

Bug description:
  Hi,

  Ubuntu 24.04 is currently set to use OpenSSL 3.0.13 which is now quite
  a bit behind the latest patch level on that OpenSSL branch, namely
  3.0.17.  There are a number of fixes between 3.0.13 and 3.0.17 which
  are listed here:

  https://github.com/openssl/openssl/blob/openssl-3.0/CHANGES.md#openssl-30

  To highlight one example vulnerability, which looks potentially
  serious:

  Changes between 3.0.14 and 3.0.15 [3 Sep 2024]
  "Applications performing certificate name checks (e.g., TLS clients checking server certificates) may attempt to read an invalid memory address when comparing the expected name with an other Name subject alternative name of an X.509 certificate. This may result in an exception that terminates the application program."

  Thanks!
  David
