CVE-2026-44394

A flaw was found in OpenStack Keystone. The federated token rescoping mechanism does not correctly propagate the original token's expiry to newly issued tokens. This allows a federated user to repeatedly rescope a token before it expires, effectively maintaining indefinite access and bypassing...

pyasn1: pyasn1 Vulnerable to Denial of Service via Unbounded Recursion

An unbounded recursion flaw has been discovered in the pypi pyasn1 library. This uncontrolled recursion occurs when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing nested SEQUENCE 0x30 or SET 0x31 tags with Indefinite Length 0x80 markers. Thi...

CVE-2026-44378

A flaw was found in Botan, a C++ cryptography library. A remote attacker could exploit this vulnerability by sending specially crafted Basic Encoding Rules BER data with indefinite length encodings. This could cause quadratic behavior in the parser, leading to a denial of service DoS due to...

SUSE CVE-2026-44378

Botan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. Such BER encodings were accepted even in structures which are required to be encoded as DER, which...

GHSA-WHQR-FGM5-X77Q OpenStack Keystone's federated token rescoping mechanism doesn't propagate the original token's expiry to the newly issued token

An issue was discovered in OpenStack Keystone before 29.0.2. The Keystone federated token rescoping mechanism does not propagate the original token's expiry to the newly issued token. When a federated user rescopes a token via POST /v3/auth/tokens, the handlescopedtoken function in the mapped...

OpenStack Keystone 安全漏洞

OpenStack Keystone is a core authentication component library of the OpenStack open-source project. Versions of OpenStack Keystone prior to 29.0.2 contained security vulnerabilities. These vulnerabilities stemmed from the joint token revalidation mechanism, which did not propagate the expiration...
