This\nwould result in corrupted output, contrary to expectations. This issue only\naffected Ubuntu 18.04 LTS. (CVE-2023-23931)\n\nIt was discovered that python-cryptography reported the outcome of\ndecrypting PKCS#7 enveloped data in distinguishable ways, and with\nobservable timing differences. A remote attacker could possibly use this\nissue to recover the key used to encrypt the message contents, and obtain\nsensitive information. This issue only affected Ubuntu 26.04 LTS.\n(CVE-2026-69247)\n\nJack Lloyd discovered that python-cryptography incorrectly handled wildcard\nDNS names when enforcing the name constraints of a certificate authority. A\nremote attacker could possibly use this issue to have an invalid\ncertificate chain accepted, and use names outside of the permitted ones.\nThis issue only affected Ubuntu 26.04 LTS. (CVE-2026-69248)\n\nSamuel Judson discovered that python-cryptography incorrectly handled\ncertificate chains that contained duplicate certificates. A remote attacker\ncould possibly use this issue to cause python-cryptography to use excessive\nresources, leading to a denial of service. This issue only affected Ubuntu\n26.04 LTS.
