Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU51248
Risk: Medium
CVSSv3.1: 6.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-25097
CWE-ID:
CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to preform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests. 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 squid3 to the latest version.

EUVDB-ID: #VU53017
Risk: Medium
CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-28651
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation when resolving "urn:" resource identifiers. A remote attacker can trick a user behind the proxy server to click on a specially crafted "urn:" link that leads to a server under attacker's control and force Squid to consume arbitrarily large amounts of memory on the server.
MitigationUpdate the affected package squid3 to the latest version.
