Chainguard: openstack-keystone-2026.2: security update to 30.0.1_git20261017-r5

high Tenable Cloud Security Plugin ID 478120

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. From 0.3.3 until 0.6.5, schemaless container decoding stores
 every decoded component's TagSet in a growing set even though only one-versus-multiple tag types must be
 distinguished. Attacker-controlled BER, CER, or DER input contains many distinct long tag IDs whose TagSet
 hashes collide. Each later set insertion compares against an increasing number of earlier colliding tags
 in ConstructedPayloadDecoderBase._decodeComponentsSchemaless, producing quadratic CPU work while decoded
 values and order remain valid. Repeated inputs can exhaust decoder CPU and reduce service availability.
 This issue is fixed in version 0.6.5. (CVE-2026-119194)

Solution

Update the openstack-keystone-2026.2 library and its related packages to version 30.0.1_git20261017-r5 or later.
