Description Lubomir Kundrak 2007-04-03 18:05:30 UTC 
Description of problem:

According to an iDefense advisory (see the URL), ImageMagick is vulnerable
to heap overflow flaws that can be triggered with crafted DCM and XWD files
and exploited to execute arbitrary code.

Version-Release number of selected component (if applicable):

        FC6 (6.2.8.0-3.fc6.1)
        FC5 (6.2.5.4-4.2.1.fc5.7)
        RHEL5 (6.2.8.0-3.el5.4)
        RHEL4 (6.0.7.1-17)
        RHEL3 (5.5.6-25)
        RHEL2.1 (5.3.8-18)

How reproducible:

Reproducers are not available at the time.

Additional info:

There are actually three bugs, one in DCM coder and two in XWD.
I attach my attempt to backport the fixes.

Comment 4 Norm Murray 2007-04-05 05:56:01 UTC 
Patches are slightly incorrect. 

RHEL 2.1 and RHEL 3 - need 3 args to ThrowReaderException and don't have
AcquireMagickMemory. 

All patches have a memory leak in the first hunk of the xwd.c patch as they
weren't removing the old memory allocation for comment, just adding a new one at
the end of their insertion.
