Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU44064

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-2012-2320

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

ConnMan before 0.85 does not ensure that netlink messages originate from the kernel, which allows remote attackers to bypass intended access restrictions and cause a denial of service via a crafted netlink message.

Mitigation

Update the affected packages.
net-misc/connman to version: 1.0-r1

Vulnerable software versions

Gentoo Linux: All versions

2) Input validation error

EUVDB-ID: #VU44065

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2012-2321

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

CVE-ID: CVE-2012-2322

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.
