Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Improper Certificate Validation
EUVDB-ID: #VU82906
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2023-46724
CWE-ID:
CWE-295 - Improper Certificate Validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation when processing a specially crafted SSL Certificate in a server certificate chain. A remote attacker can initiate a TLS Handshake with a specially crafted SSL certificate and perform a denial of service (DoS) attack.
Update the affected package squid to the latest version.

2) Inconsistent interpretation of HTTP requests
EUVDB-ID: #VU82315
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2023-46846
CWE-ID:
CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests when parsing HTTP/1.1 and ICAP messages. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
MitigationUpdate the affected package squid to the latest version.
