SCA: security update for pyasn1 (GHSA-8ppf-4f7h-5ppj)

high Tenable Cloud Security Plugin ID 445075

Description

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

 - pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER, CER, and DER decoders process
 OBJECT IDENTIFIER and RELATIVE-OID values in quadratic time relative to the number of arcs, so a small
 crafted payload containing an OID with many arcs consumes excessive CPU per decode() call and can deny
 service to applications that decode untrusted ASN.1 data. The corresponding encoders have the same
 quadratic behavior when an application re-encodes previously decoded attacker-supplied values. This issue
 is fixed in version 0.6.4. (CVE-2026-59885)

Solution

Update the pyasn1 library and its related packages to version 0.6.4 or later.
