curl: curl: Denial of Service via WebSocket PING flood
A flaw was found in curl. A malicious server can exploit this vulnerability by sending rapid, sequential WebSocket PING messages. Due to a lack of an upper bound on memory allocation for unacknowledged frames, curl can be forced to exhaust all available memory, leading to a denial of service...
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: Double-free vulnerability in SASL authentication
A flaw was found in curl. The logic handling SASL Simple Authentication and Security Layer authentication could lead to a double-free vulnerability. This occurs because the GSASL context may be deallocated twice without clearing the pointer, potentially leading to memory corruption. An attacker...
curl: curl: SSH host verification bypass when using schemeless URLs with SFTP/SCP
A flaw was found in curl. When a user invokes curl with a schemeless URL and specifies SFTP SSH File Transfer Protocol or SCP Secure Copy Protocol as the default protocol, the tool layer fails to initialize critical SSH security options. This bypasses host verification, allowing curl to connect t...
curl: curl: Information disclosure via incorrect .netrc password lookup
A flaw was found in curl. When curl is configured to use a .netrc file for credentials and a URL is provided with a username but no password, curl may incorrectly retrieve and use the password for a different user from the .netrc file for the same host. This could lead to unauthorized information...
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: 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...
libcurl: libcurl: Certificate validation bypass due to incorrect connection reuse
A flaw was found in curl. When libcurl reuses a connection from its connection pool, an easy handle that initially used default native Certificate Authority CA trust may continue to trust the native platform store. This occurs even after the application has switched that same handle to custom CA...
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: Insecure connection establishment due to TLS configuration mismatch
A flaw was found in curl. When a new data transfer attempts to upgrade its connection using STARTTLS, it may incorrectly reuse an existing live connection. This reuse can occur even if the Transport Layer Security TLS configuration of the new transfer does not match the existing connection,...
curl: libcurl: curl/libcurl: Remote denial of service via QUIC UDP receive function vulnerability
A flaw was found in curl and libcurl. A malicious HTTP/3 server can exploit an issue in the QUIC UDP receive function by continuously streaming empty UDP datagrams. This can lead to a remote denial of service DoS against a curl or libcurl client, as the helper function discards zero-length UDP...
curl: curl: Man-in-the-middle attack via SSH host key bypass
A flaw was found in curl. When a libcurl-based application uses SCP:// or SFTP:// for transfers and employs the CURLOPTSSHKEYFUNCTION callback, it may silently accept an untrusted server. This occurs if the server's host key type differs from the one stored in the knownhosts file. The callback...
libcurl: libcurl: Information disclosure due to persistent Referer header
A flaw was found in libcurl. This vulnerability causes the HTTP Referer header to persist even after it has been explicitly cleared. This can lead to the previous referrer string being unintentionally reused and sent in subsequent requests, potentially disclosing sensitive information to unintend...
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...
curl: curl: Cookie injection via malicious HTTP server using super cookies
A flaw was found in curl's cookie parsing logic. A malicious HTTP server can exploit this by setting 'super cookies' that bypass the Public Suffix List check. This allows an attacker-controlled origin to inject cookies that curl then transmits to unrelated third-party domains, leading to...
nodejs: Node.js WebCrypto: Denial of Service via large input to subtle.encrypt()
A flaw was found in the Node.js WebCrypto implementation. A remote attacker could exploit this vulnerability by providing an input to the subtle.encrypt function that is a multiple of 2 gigabytes GiB. This could lead to a denial of service DoS by crashing the Node.js process...
nodejs: Node.js: Authentication bypass due to TLS hostname handling and unicode dot separator mismatch
A flaw was found in Node.js. This flaw involves a mismatch in how Node.js handles TLS Transport Layer Security hostnames and unicode dot separators during authentication. This mismatch can lead to a wildcard-depth authentication bypass. An attacker could exploit this to bypass intended security...
