libcurl: libcurl: Security feature bypass due to improper mTLS connection reuse
A flaw was found in curl. The libcurl library, used for transferring data with URLs, could improperly reuse existing network connections. This occurred even when changes to mutual Transport Layer Security mTLS settings, particularly those for client certificates, should have prevented such reuse...
curl: curl: Authentication bypass due to incorrect connection reuse with Negotiate authentication
A flaw was found in curl. When an application uses libcurl to make multiple Negotiate-authenticated HTTP or HTTPS requests to the same server with different credentials, libcurl may incorrectly reuse an existing connection. This logical error can cause a subsequent request to be sent using the...
curl: libcurl: Unauthorized connection reuse due to a logical error
A flaw was found in libcurl. A logical error in the connection pooling mechanism may cause libcurl to reuse an authenticated connection for an unintended service. This could allow an application to wrongfully reuse an existing connection to the same server that was authenticated for a different...
curl: libcurl: Improper certificate validation due to cached TLS settings reuse
A flaw was found in libcurl. When handling secure connections TLS and reusing connection settings, libcurl could incorrectly apply a cached security setting related to certificate chain validation. This could allow libcurl to accept a server's security certificate that it should have otherwise...
curl: Information disclosure due to uncleared proxy authentication state
A flaw was found in libcurl. When reusing a libcurl handle for sequential transfers with environment-variable proxy configuration, the library does not properly clear the proxy authentication state. This oversight can lead to the unintended disclosure of Proxy-Authorization headers to an incorrec...
libcurl: libcurl: Information disclosure due to failure to clear proxy authentication credentials
A flaw was found in curl. When libcurl is instructed to clear proxy authentication credentials, it fails to do so, leaving the old credentials available. This could lead to the unintended reuse of sensitive proxy authentication credentials for subsequent network transfers, potentially resulting i...
curl: curl: Information disclosure via incorrect Digest authentication header reuse
A flaw was found in curl. When libcurl performs a transfer to an HTTP origin using Digest authentication and then reuses the same connection handle for a subsequent transfer to a different origin, it may incorrectly send the authentication header intended for the first origin to the second. This...
