Original advisory details:

 It was discovered that curl incorrectly handled cookies when redirected
 from secure to insecure connections. An attacker could possibly use this
 issue to cause a denial of service, or obtain sensitive information.
 This issue only affected Ubuntu 25.10. (CVE-2025-9086)

 Calvin Ruocco discovered that curl did not properly handle WebSocket
 communications under certain circumstances. A malicious server could
 possibly use this issue to poison proxy caches with malicious content.
 This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10.
 (CVE-2025-10148)

 Stanislav Fort discovered that wcurl did not properly handle URLs with
 certain encoded characters. If a user were tricked into processing
 a specially crafted URL, an attacker could possibly use this issue to
 write files outside the intended directory. This issue only affected
 Ubuntu 25.10. (CVE-2025-11563)

 Stanislav Fort discovered that curl did not properly validate pinned
 public keys under certain circumstances. A remote attacker could
 possibly use this issue to perform a machine-in-the-middle attack. This
 issue only affected Ubuntu 25.10.(CVE-2025-13034)

 Stanislav Fort discovered that curl did not properly manage TLS options
 when performing LDAP over TLS transfers in multi-threaded environments.
 Under certain circumstances, certificate verification could be
 unintentionally and unknowingly disabled. (CVE-2025-14017)

 It was discovered that curl incorrectly handled Oauth2 bearer tokens
 when following redirects. A remote attacker could possibly use this
 issue to obtain authentication credentials. (CVE-2025-14524)

 Stanislav Fort discovered that curl did not properly validate TLS
 certificates when reusing connections. A remote attacker could possibly
 use this issue to bypass expected certificate verification. This issue
 only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2025-14819)

 Harry Sintonen discovered that curl did not properly validate SSH host
 keys when performing SSH-based file transfers. This issue could lead to
 unintended bypass of custom known_hosts file. This issue only
 affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2025-15079)

 Harry Sintonen discovered that curl built with libssh did not properly
 handle authentication when performing SSH-based file transfers. This
 could result in unintended authentication operations. This issue only
 affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2025-15224)");
