USN90-1 : imagemagick vulnerability Vulnerability Scan
Vulnerability Scan Summary imagemagick vulnerability
Detailed Explanation for this Vulnerability Test
Synopsis :
These remote packages are missing security patches :
- imagemagick
- libmagick++6
- libmagick++6-dev
- libmagick6
- libmagick6-dev
- perlmagick
Description :
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 rights).
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.
Solution :
Upgrade to :
- imagemagick-6.0.2.5-1ubuntu1.4 (Ubuntu 4.10)
- libmagick++6-6.0.2.5-1ubuntu1.4 (Ubuntu 4.10)
- libmagick++6-dev-6.0.2.5-1ubuntu1.4 (Ubuntu 4.10)
- libmagick6-6.0.2.5-1ubuntu1.4 (Ubuntu 4.10)
- libmagick6-dev-6.0.2.5-1ubuntu1.4 (Ubuntu 4.10)
- perlmagick-6.0.2.5-1ubuntu1.4 (Ubuntu 4.10)
Threat Level: High
