Package: imagemagick
Version: 6:6.0.6.2-1.4
Severity: grave
Tags: security patch
Justification: user security hole

A buffer overflow in imagemagick's EXIF parsing routine was fixed in
version 6.1.0: Trying to query EXIF information of a malicious image
file might result in execution of arbitrary code. The fix in 6.1.0 was
slightly buggy. An improved version is to appear in 6.1.2, and is also
attached to this report. The security team has assigned CAN-2004-0981 to
this issue. Our versions in woody and sarge/sid are affected.

Ryuichi, unless you object I'd like to prepare NMUs 4:5.4.4.5-1woody4
and 6:6.0.6.2-1.5 to resolve this issue.

Regards,

Daniel.
