TITLE:
GraphicsMagick PALM and DCM Buffer Overflows

SECUNIA ADVISORY ID:
SA22569

VERIFY ADVISORY:
http://secunia.com/advisories/22569/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
GraphicsMagick 1.x
http://secunia.com/product/3764/

DESCRIPTION:
Some vulnerabilities have been reported in GraphicsMagick, which can
be exploited by malicious people to cause a DoS (Denial of Service)
and potentially compromise a vulnerable system.

1) A boundary error within the "ReadDCMImage()" function in
coders/dcm.c can be exploited to cause a buffer overflow when
processing specially crafted DCM images.

2) Several boundary errors within the "ReadPALMImage()" function in
coders/palm.c can be exploited to cause heap-based buffer overflows
when processing specially crafted PALM images.

Successful exploitation may allow the execution of arbitrary code.

SOLUTION:
Do not open untrusted PALM and DCM images.
