Alpine: python3: security update to 3.10.9-r0

critical Tenable Self-Hosted Container Security Plugin ID 406750

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer
overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties.
This occurs in the sponge function interface. (CVE-2022-37454)

- Python 3.9.x before 3.9.16 and 3.10.x before 3.10.9 on Linux allows local privilege escalation in a non-
default configuration. The Python multiprocessing library, when used with the forkserver start method on
Linux, allows pickles to be deserialized from any user in the same machine local network namespace, which
in many system configurations means any user on the same machine. Pickles can execute arbitrary code.
Thus, this allows for local user privilege escalation to the user that any forkserver process is running
as. Setting multiprocessing.util.abstract_sockets_supported to False is a workaround. The forkserver start
method for multiprocessing is not the default start method. This issue is Linux specific because only
Linux supports abstract namespace sockets. CPython before 3.9 does not make use of Linux abstract
namespace sockets by default. Support for users manually specifying an abstract namespace socket was added
as a bugfix in 3.7.8 and 3.8.3, but users would need to make specific uncommon API calls in order to do
that in CPython before 3.9. (CVE-2022-42919)

- An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path
when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name
being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by
remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger
excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname.
For example, the attack payload could be placed in the Location header of an HTTP response with status
code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16. (CVE-2022-45061)
