Security Bulletin
This security bulletin contains one medium risk vulnerability.
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.
Update the affected package curl to the latest version.
Vulnerable software versionsUbuntu: 14.04 - 16.04
