[Pkg-gmagick-im-team] Bug#823542: imagemagick-common: please mitigate CVE-2016-3714, remote arbitrary code execution during handling of delegates

[Simon McVittie]

Package: imagemagick-common
Version: 8:6.8.9.9-7+b2
Severity: grave
Tags: security
Justification: user security hole

I'm sure you're already aware of
<https://security-tracker.debian.org/tracker/CVE-2016-3714>, the most serious
of the recent batch of ImageMagick vulnerabilities published at
<https://imagetragick.com/>.

There does not seem to be a full upstream fix yet, but it seems the
vulnerabilities can be mitigated by altering the policy.xml file in
imagemagick-common. The cost of this mitigation is that some obscure
file formats, and some features that perhaps shouldn't have been
implemented in the first place, are disabled.

Regards,
    S
