Ubuntu Security Notice USN-3176-1
January 23, 2017

pcsc-lite vulnerability

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

- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS


PCSC-Lite could be made to crash or run programs as an administrator
if it received specially crafted input.

Software Description:
- pcsc-lite: Middleware to access a smart card using PC/SC


Peter Wu discovered that the PC/SC service did not correctly handle certain
resources. A local attacker could use this issue to cause PC/SC to crash,
resulting in a denial of service, or possibly execute arbitrary code with
root privileges.

Update instructions:

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

Ubuntu 16.10:
  pcscd                           1.8.14-1ubuntu1.16.10.1

Ubuntu 16.04 LTS:
  pcscd                           1.8.14-1ubuntu1.16.04.1

Ubuntu 14.04 LTS:
  pcscd                           1.8.10-1ubuntu1.1

Ubuntu 12.04 LTS:
  pcscd                           1.7.4-2ubuntu2.1

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