ConnMan: Multiple vulnerabilities — GLSA 201205-02

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

Affected Packages

net-misc/connman on all architectures
Affected versions < 1.0-r1
Unaffected versions >= 1.0-r1

Background

ConnMan provides a daemon for managing Internet connections.

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:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-misc/connman-1.0-r1"
