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

high Tenable Cloud Security Plugin ID 478116

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 0.6.5, constructed string and indefinite-length ANY
 decoding repeatedly concatenates each fragment onto a growing bytes value. Attacker-controlled BER or CER
 data can use many constructed OCTET STRING or character-string fragments. DER rejects constructed OCTET
 STRING without a schema, but accepts its definite-length form when asn1Spec selects univ.OctetString; it
 also accepts constructed character strings such as UTF8String without a schema, even though those
 encodings are not valid DER. The separate indefinite-length ANY path is reachable in BER and CER when
 asn1Spec selects univ.Any; DER rejects indefinite lengths. OctetStringPayloadDecoder uses growing header
 concatenation and AnyPayloadDecoder.indefLenValueDecoder uses growing chunk concatenation, repeatedly
 copying an increasing prefix and causing quadratic work. A sufficiently fragmented value can occupy
 decoding workers and cause CPU exhaustion without confidentiality or integrity impact. This issue is fixed
 in version 0.6.5. (CVE-2026-119195)

Solution

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