Description

This security bulletin contains information about 3 vulnerabilities.


1) Resource management error (CVE-ID: CVE-2010-4352)

CWE-ID: CWE-399 - Resource Management Errors

CVSSv4: 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


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.


2) Input validation error (CVE-ID: cve-2011-2200)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 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


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.


3) Link following (CVE-ID: CVE-2011-2533)

CWE-ID: CWE-59 - Improper Link Resolution Before File Access ('Link Following')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.

The configure script in D-Bus (aka DBus) 1.2.x before 1.2.28 allows local users to overwrite arbitrary files via a symlink attack on an unspecified file in /tmp/.
