Alpine: libcrypto3, multiple openssl packages: security update to 3.2.1-r2

medium Tenable Self-Hosted Container Security Plugin ID 424306

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Issue summary: Some non-default TLS server configurations can cause unbounded memory growth when
 processing TLSv1.3 sessions Impact summary: An attacker may exploit certain server configurations to
 trigger unbounded memory growth that would lead to a Denial of Service This problem can occur in TLSv1.3
 if the non-default SSL_OP_NO_TICKET option is being used (but not if early_data support is also configured
 and the default anti-replay protection is in use). In this case, under certain conditions, the session
 cache can get into an incorrect state and it will fail to flush properly as it fills. The session cache
 will continue to grow in an unbounded manner. A malicious client could deliberately create the scenario
 for this failure to force a Denial of Service. It may also happen by accident in normal operation. This
 issue only affects TLS servers supporting TLSv1.3. It does not affect TLS clients. The FIPS modules in
 3.2, 3.1 and 3.0 are not affected by this issue. OpenSSL 1.0.2 is also not affected by this issue.
