An issue was addressed with improved handling of temporary files. This issue is fixed in macOS Monterey 12.7.2, macOS Ventura 13.6.3, iOS 17.2 and iPadOS 17.2, iOS 16.7.3 and iPadOS 16.7.3, macOS Sonoma 14.2. An app may be able to modify protected parts of the file system.
When a protocol selection parameter option disables all protocols without adding any then the default set of protocols would remain in the allowed set due to an error in the logic for removing protocols. The below command would perform a request to curl.se with a plaintext protocol which has been explicitly disabled. curl --proto -all,-http http://curl.se The flaw is only present if the set of selected protocols disables the entire set of available protocols, in itself a command with no practical use and therefore unlikely to be encountered in real situations. The curl security team has thus assessed this to be low severity bug.
libcurl skips the certificate verification for a QUIC connection under certain conditions, when built to use wolfSSL. If told to use an unknown/bad cipher or curve, the error path accidentally skips the verification and returns OK, thus ignoring any certificate problems.
When an application tells libcurl it wants to allow HTTP/2 server push, and the amount of received headers for the push surpasses the maximum allowed limit (1000), libcurl aborts the server push. When aborting, libcurl inadvertently does not free all the previously allocated headers and instead leaks the memory. Further, this error condition fails silently and is therefore not easily detected by an application.
libcurl did not check the server certificate of TLS connections done to a host specified as an IP address, when built to use mbedTLS. libcurl would wrongly avoid using the set hostname function when the specified hostname was given as an IP address, therefore completely skipping the certificate check. This affects all uses of TLS protocols (HTTPS, FTPS, IMAPS, POPS3, SMTPS, etc).
A validation issue was addressed with improved input sanitization. This issue is fixed in macOS Monterey 12.7.4, macOS Ventura 13.6.5, macOS Sonoma 14.4, visionOS 1.1, iOS 17.4 and iPadOS 17.4, iOS 16.7.6 and iPadOS 16.7.6, tvOS 17.4. An application may be able to read restricted memory.
A memory corruption vulnerability was addressed with improved locking. This issue is fixed in macOS Monterey 12.7.4, macOS Ventura 13.6.5, macOS Sonoma 14.4, visionOS 1.1, iOS 17.4 and iPadOS 17.4, watchOS 10.4, iOS 16.7.6 and iPadOS 16.7.6, tvOS 17.4. An app may be able to cause unexpected system termination or write kernel memory.
