Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Security features bypass
EUVDB-ID: #VU70457
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-43551
CWE-ID:
CWE-254 - Security Features
Exploit availability: No
DescriptionThe vulnerability allows an attacker to gain access to sensitive information.
The vulnerability exists in the way curl handles IDN characters in hostnames. The HSTS mechanism could be bypassed if the hostname in the given URL first uses IDN characters that get replaced to ASCII counterparts as part of the IDN conversion. Then in a subsequent request it does not detect the HSTS state and makes a clear text transfer.
MitigationUpdate the affected package curl to the latest version.

2) Use-after-free
EUVDB-ID: #VU70456
Risk: Low
CVSSv4.0: 0.2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-43552
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error while processing denied requests from HTTP proxies when using SMB or TELNET protocols. A remote attacker can trigger a use-after-free error and crash the application.
Update the affected package curl to the latest version.
