                            libsndfile Vulnerability
                     [Debian Security Advisory DSA-1442-1]

______________________________________________________________________________
PROBLEM:       It has been discovered that libsndfile, a library for reading / 
               writing audio files performs insufficient boundary checks when 
               processing FLAC files, which may lead to the execution of 
               arbitrary code. 
PLATFORM:      Debian GNU/Linux 4.1 (stable) 
DAMAGE:        May lead to the execution of arbitrary code. 
SOLUTION:      Upgrade to the appropriate version. 
______________________________________________________________________________
VULNERABILITY  The risk is LOW. May lead to the execution of arbitrary code. 
ASSESSMENT:
