Ubuntu 16.04 ESM / 18.04 ESM : Python vulnerabilities (USN-6513-1)

high Nessus Plugin ID 186226

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6513-1 advisory.

 It was discovered that Python incorrectly handled certain plist files. If a user or an automated system were tricked into processing a specially crafted plist file, an attacker could possibly use this issue to consume resources, resulting in a denial of service. (CVE-2022-48564)

 It was discovered that Python instances of ssl.SSLSocket were vulnerable to a bypass of the TLS handshake.
 An attacker could possibly use this issue to cause applications to treat unauthenticated received data before TLS handshake as authenticated data after TLS handshake. (CVE-2023-40217)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected packages.
