Поиск уязвимостей

Уязвимость библиотеки для обмена идентификационными данными по стандарту SAML2 PySAML2, связанная с некорректным подтверждением криптографической подписи данных, позволяющая нарушителю обойти проверку подписи и получить доступ к защищаемой информации

ALT-PU-2023-1534: package `python3-module-pysaml2` update to version 7.4.1-alt1

ALT-PU-2023-1286: package `python3-module-pysaml2` update to version 7.4.0-alt1

PySAML2 before 5.0.0 does not check that the signature in a SAML document is enveloped and thus signature wrapping is effective, i.e., it is affected by XML Signature Wrapping (XSW). The signature information and the node/object that is signed can be in different places and thus the signature verification will succeed, but the wrong data will be used. This specifically affects the verification of assertion that have been signed.
