Summary:<\/p>\n

Details:<\/p>\n
USN-6663-1 provided a security update for OpenSSL.
This update provides the corresponding update for
Ubuntu 24.04 LTS.<\/p>\n
Original advisory details:<\/p>\n
As a security improvement, OpenSSL will now
return deterministic random bytes instead of an error
when detecting wrong padding in PKCS#1 v1.5 RSA
to prevent its use in possible Bleichenbacher timing attacks.<\/p>\n

After a standard system update you need to reboot your computer to make
all the necessary changes.<\/p>\n
