Amazon Linux 2 : python38 (ALASPYTHON3.8-2023-009)

critical Nessus Plugin ID 182009

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of python38 installed on the remote host is prior to 3.8.5-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2PYTHON3.8-2023-009 advisory.

- The CryptProtectMemory function in cng.sys (aka the Cryptography Next Generation driver) in the kernel- mode drivers in Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1, when the CRYPTPROTECTMEMORY_SAME_LOGON option is used, does not check an impersonation token's level, which allows local users to bypass intended decryption restrictions by leveraging a service that (1) has a named-pipe planting vulnerability or (2) uses world-readable shared memory for encrypted data, aka CNG Security Feature Bypass Vulnerability or MSRC ID 20707. (CVE-2015-0010)

- In Python 3 through 3.9.0, the Lib/test/multibytecodec_support.py CJK codec tests call eval() on content retrieved via HTTP. (CVE-2020-27619)

- In Python before 3,9,5, the ipaddress library mishandles leading zero characters in the octets of an IP address string. This (in some situations) allows attackers to bypass access control that is based on IP addresses. (CVE-2021-29921)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update python38' to update your system.
