Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Expected behavior violation
EUVDB-ID: #VU68746
Risk: Medium
CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-32221
CWE-ID:
CWE-440 - Expected Behavior Violation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to force unexpected application behavior.
The vulnerability exists due to a logic error for a reused handle when processing subsequent HTTP PUT and POST requests. 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, such behavior can influence application flow and force unpredictable outcome.

2) Input validation error
EUVDB-ID: #VU73826
Risk: Low
CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-27533
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to manipulate requests.
The vulnerability exists due to missing documentation of the TELNET protocol support and the ability to pass on user name and "telnet options" for the server negotiation. A remote attacker can manipulate the connection sending unexpected data to the server via the affected client.

3) Expected behavior violation
EUVDB-ID: #VU76238
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-28322
CWE-ID:
CWE-440 - Expected Behavior Violation
Exploit availability: No
DescriptionThe 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.
