Description

This security bulletin contains information about 1 security vulnerability.


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.


Remediation

Install update from vendor's website.
