23 January 2017

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



  • 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
Ubuntu 16.04
Ubuntu 14.04
Ubuntu 12.04

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