net-snmp vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS


Net-SNMP could be made to crash or run programs if it received specially
crafted network traffic.

Software Description:
- net-snmp: SNMP (Simple Network Management Protocol) server and applications


It was discovered that Net-SNMP incorrectly handled certain trap messages
when the -OQ option was used. A remote attacker could use this issue to
cause Net-SNMP to crash, resulting in a denial of service. (CVE-2014-3565)

Qinghao Tang discovered that Net-SNMP incorrectly handled SNMP PDU parsing
failures. A remote attacker could use this issue to cause Net-SNMP to
crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2015-5621)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 15.04:
  libsnmp30                       5.7.2~dfsg-8.1ubuntu5.1

Ubuntu 14.04 LTS:
  libsnmp30                       5.7.2~dfsg-8.1ubuntu3.1

Ubuntu 12.04 LTS:
  libsnmp15                       5.4.3~dfsg-2.4ubuntu1.3

In general, a standard system update will make all the necessary changes.
