2) Input validation error (CVE-ID: CVE-2024-45341)

The vulnerability exists due to incorrect handling of URI name constraint in certificate chains. A remote attacker can create a certificate with a URI, which has a IPv6 address with a zone ID, and bypass URI name checks.

The vulnerability affects users of private PKIs which make use of URIs.


3) Memory leak (CVE-ID: CVE-2025-22866)

The vulnerability exists due to a small number of bits of secret scalars are leaked on the ppc64le architecture in crypto/internal/nistec. A local user can gain access to potentially sensitive information.


4) Input validation error (CVE-ID: CVE-2025-22870)

The vulnerability allows a remote attacker to alter application's behavior.

The vulnerability exists due to insufficient validation of an IPv6 zone ID as a hostname component, when matching hosts against proxy patterns. For instance the NO_PROXY environment variable is set to "*.example.com", a request to "[::1%25.example.com]:80` will incorrectly match and not be proxied. A remote attacker can alter application behavior and potentially  gain access to sensitive information or functionality.


5) Information disclosure (CVE-ID: CVE-2025-4673)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.
