Alpine: libcrypto3, multiple openssl packages: security update to 3.1.0-r3 (deprecated)

medium Tenable Self-Hosted Container Security Plugin ID 400067

Description

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

- Issue summary: The AES-XTS cipher decryption implementation for 64 bit ARM platform contains a bug that
could cause it to read past the input buffer, leading to a crash. Impact summary: Applications that use
the AES-XTS algorithm on the 64 bit ARM platform can crash in rare circumstances. The AES-XTS algorithm is
usually used for disk encryption. The AES-XTS cipher decryption implementation for 64 bit ARM platform
will read past the end of the ciphertext buffer if the ciphertext size is 4 mod 5 in 16 byte blocks, e.g.
144 bytes or 1024 bytes. If the memory after the ciphertext buffer is unmapped, this will trigger a crash
which results in a denial of service. If an attacker can control the size and location of the ciphertext
buffer being decrypted by an application using AES-XTS on 64 bit ARM, the application is affected. This is
fairly unlikely making this issue a Low severity one. (CVE-2023-1255)
