Security Bulletin

This security bulletin contains information about 20 vulnerabilities.

1) Expected behavior violation

EUVDB-ID: #VU68746

Risk: Medium

CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-32221

CWE-ID: CWE-440 - Expected Behavior Violation

Exploit availability: No

Description

The 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.

Mitigation

Update the affected package mysql-5.7 to the latest version.
