Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Resource management error

EUVDB-ID: #VU32841

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2010-4352

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

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

Stack consumption vulnerability in D-Bus (aka DBus) before 1.4.1 allows local users to cause a denial of service (daemon crash) via a message containing many nested variants.

Mitigation

Update the affected packages.
sys-apps/dbus to version: 1.4.12

Vulnerable software versions

Gentoo Linux: All versions

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Input validation error

EUVDB-ID: #VU32842

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: cve-2011-2200

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a local non-authenticated attacker to read and manipulate data.

The _dbus_header_byteswap function in dbus-marshal-header.c in D-Bus (aka DBus) 1.2.x before 1.2.28, 1.4.x before 1.4.12, and 1.5.x before 1.5.4 does not properly handle a non-native byte order, which allows local users to cause a denial of service (connection loss), obtain potentially sensitive information, or conduct unspecified state-modification attacks via crafted messages.

Mitigation

Update the affected packages.
sys-apps/dbus to version: 1.4.12
