Ubuntu security advisory. 
 
A buffer overflow in imagemagick's EXIF parsing routine has been 
discovered in imagemagick versions prior to 6.1.0. Trying to query 
EXIF information of a malicious image file might result in execution 
of arbitrary code with the user's privileges. 
 
Since imagemagick can be used in custom printing systems, this also 
might lead to privilege escalation (execute code with the printer 
spooler's privileges). However, Ubuntu's standard printing system does 
not use imagemagick, thus there is no risk of privilege escalation in 
a standard installation.
