Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Expected behavior violation (CVE-ID: CVE-2023-28322)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to a logic error when sending HTTP POST and PUT requests using the same handle. The libcurl can erroneously use the read callback (CURLOPT_READFUNCTION) to ask for data to send, even when the CURLOPT_POSTFIELDS option has been set, if the same handle previously was used to issue a PUT request which used that callback. As a result, the application can misbehave and either send off the wrong data or use memory after free or similar in the second transfer.
2) Improper synchronization (CVE-ID: CVE-2023-28320)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper synchronization when resolving host names using the alarm() and siglongjmp() function. A remote attacker can force the application to crash by influencing contents of the global buffer.
3) Improper certificate validation (CVE-ID: CVE-2023-28321)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to improper certificate validation when matching wildcards in TLS certificates for IDN names. A remote attacker crate a specially crafted certificate that will be considered trusted by the library.
Successful exploitation of the vulnerability requires that curl is built to use OpenSSL, Schannel or Gskit.
