Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU68748
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-42915
CWE-ID:
CWE-415 - Double Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing non-200 proxy HTTP responses for the following schemes: dict, gopher, gophers, ldap, ldaps, rtmp, rtmps, telnet. A remote attacker can trigger a double free error by forcing the application into connecting to resources that are not allowed by the configured proxy.

EUVDB-ID: #VU68749
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-42916
CWE-ID:
CWE-319 - Cleartext Transmission of Sensitive Information
Exploit availability: No
DescriptionThe 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.

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.
