This update provides the\ncorresponding update for CVE-2025-14017, CVE-2025-15079, and CVE-2025-15224\nfor Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.04\nLTS.\n\nOriginal advisory details:\n\n It was discovered that curl incorrectly handled cookies when redirected\n from secure to insecure connections. An attacker could possibly use this\n issue to cause a denial of service, or obtain sensitive information.\n This issue only affected Ubuntu 25.10. (CVE-2025-9086)\n\n Calvin Ruocco discovered that curl did not properly handle WebSocket\n communications under certain circumstances. A malicious server could\n possibly use this issue to poison proxy caches with malicious content.\n This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10.\n (CVE-2025-10148)\n\n Stanislav Fort discovered that wcurl did not properly handle URLs with\n certain encoded characters. If a user were tricked into processing\n a specially crafted URL, an attacker could possibly use this issue to\n write files outside the intended directory. This issue only affected\n Ubuntu 25.10. (CVE-2025-11563)\n\n Stanislav Fort discovered that curl did not properly validate pinned\n public keys under certain circumstances. A remote attacker could\n possibly use this issue to perform a machine-in-the-middle attack. This\n issue only affected Ubuntu 25.10.(CVE-2025-13034)\n\n Stanislav Fort discovered that curl did not properly manage TLS options\n when performing LDAP over TLS transfers in multi-threaded environments.\n Under certain circumstances, certificate verification could be\n unintentionally and unknowingly disabled. (CVE-2025-14017)\n\n It was discovered that curl incorrectly handled Oauth2 bearer tokens\n when following redirects. A remote attacker could possibly use this\n issue to obtain authentication credentials. (CVE-2025-14524)\n\n Stanislav Fort discovered that curl did not properly validate TLS\n certificates when reusing connections. A remote attacker could possibly\n use this issue to bypass expected certificate verification. This issue\n only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2025-14819)\n\n Harry Sintonen discovered that curl did not properly validate SSH host\n keys when performing SSH-based file transfers. This issue could lead to\n unintended bypass of custom known_hosts file. This issue only\n affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2025-15079)\n\n Harry Sintonen discovered that curl built with libssh did not properly\n handle authentication when performing SSH-based file transfers. This\n could result in unintended authentication operations. This issue only\n affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2025-15224)",
