openssl: updated to 3.3.1
Changes between 3.3.0 and 3.3.1 [4 Jun 2024]
* Fixed potential use after free after SSL_free_buffers() is called.
The SSL_free_buffers function is used to free the internal OpenSSL
buffer used when processing an incoming record from the network.
The call is only expected to succeed if the buffer is not currently
in use. However, two scenarios have been identified where the buffer
is freed even when still in use.
The first scenario occurs where a record header has been received
from the network and processed by OpenSSL, but the full record body
has not yet arrived. In this case calling SSL_free_buffers will succeed
even though a record has only been partially processed and the buffer
is still in use.
The second scenario occurs where a full record containing application
data has been received and processed by OpenSSL but the application has
only read part of this data. Again a call to SSL_free_buffers will
succeed even though the buffer is still in use.
([CVE-2024-4741])
* Fixed an issue where checking excessively long DSA keys or parameters may
be very slow.
Applications that use the functions EVP_PKEY_param_check() or
EVP_PKEY_public_check() to check a DSA public key or DSA parameters may
experience long delays. Where the key or parameters that are being checked
have been obtained from an untrusted source this may lead to a Denial of
Service.
To resolve this issue DSA keys larger than OPENSSL_DSA_MAX_MODULUS_BITS
will now fail the check immediately with a DSA_R_MODULUS_TOO_LARGE error
reason.
