Tavis Ormandy discovered a format string vulnerability in
ImageMagick's file name handling. Specially crafted file names could
cause a program using ImageMagick to crash, or possibly even cause
execution of arbitrary code.
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.
ImageMagick is also commonly used by web frontends; if these accept
image uploads with arbitrary file names, this could also lead to
remote privilege escalation.
Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected packages.
