Severity: normal
Exploitable: local
Date: January 21, 2014
Bug(s): #349561
ID: 201401-17

Synopsis

A vulnerability in PCSC-Lite could result in execution of arbitrary
code or Denial of Service.


Background

PCSC-Lite is a PC/SC Architecture smartcard middleware library.

Affected Packages

Package: sys-apps/pcsc-lite
Vulnerable: < 1.6.6
Unaffected: >= 1.6.6
Architectures: All supported architectures


Description

PCSC-Lite contains a stack-based buffer overflow in the ATRDecodeAtr
function in the
Answer-to-Reset Handler (atrhandler.c).


Impact

A physically proximate attacker could execute arbitrary code or cause a
Denial of Service condition.


Workaround

There is no known workaround at this time.

Resolution

All PCSC-Lite users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=sys-apps/pcsc-lite-1.6.6"
   
NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since January 10, 2011. It is likely that your system is
already no longer affected by this issue.
