SB2022102658 - SUSE update for curl

Description

This security bulletin contains information about 2 secuirty vulnerabilities.

1) Expected behavior violation (CVE-ID: CVE-2022-32221)

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.

2) Input validation error (CVE-ID: CVE-2022-35252)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the way curl handles cookies with control codes (byte values below 32). When cookies that contain such control codes are later sent back to an HTTP(S) server, it might make the server return a 400 response, effectively allowing a "sister site" to deny service to siblings.

Remediation

Install update from vendor's website.
