SB2022102703 - 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) Cleartext transmission of sensitive information (CVE-ID: CVE-2022-42916)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to an error when parsing URL with IDN characters that get replaced to ASCII counterparts as part of the IDN conversion. A remote attacker can bypass curl's HSTS check and trick it into using unencrypted HTTP protocol.
