Gentoo Linux Security Advisory

Title: ConnMan: Multiple vulnerabilities (GLSA 201205-02)
Severity: normal
Exploitable: remote
Date: May 15, 2012
Bug(s): #415415
ID: 201205-02

Synopsis

Multiple vulnerabilities have been found in ConnMan, allowing
attackers to execute arbitrary code or cause Denial of Service.


Background

ConnMan provides a daemon for managing Internet connections.

Affected Packages

Package: net-misc/connman
Vulnerable: < 1.0-r1
Unaffected: >= 1.0-r1
Architectures: All supported architectures


Description

Multiple vulnerabilities have been found in ConnMan:
  • Errors in inet.c and rtnl.c prevent ConnMan from checking the origin
    of netlink messages (CVE-2012-2320).
  • ConnMan does not properly check for shell escapes when requesting a
    hostname via DHCP (CVE-2012-2321).
  • An infinite loop error exists in client.c (CVE-2012-2322).


Impact

A remote attacker could execute arbitrary code with the privileges of
the process or cause a Denial of Service condition.


Workaround

There is no known workaround at this time.

Resolution

All ConnMan users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=net-misc/connman-1.0-r1"
