TITLE:
ImageMagick XCF and Sun Rasterfile Buffer Overflows

SECUNIA ADVISORY ID:
SA21615

VERIFY ADVISORY:
http://secunia.com/advisories/21615/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
From remote

SOFTWARE:
ImageMagick 6.x
http://secunia.com/product/3763/
ImageMagick 5.x
http://secunia.com/product/1791/

DESCRIPTION:
Tavis Ormandy has reported some vulnerabilities in ImageMagick, which
potentially can be exploited by malicious people to compromise a
vulnerable system.

1) Boundary errors within the "DecodeBitmap()" function and the
"ReadSUNImage()" function in sun.c can be exploited to cause
heap-based buffer overflows when processing specially crafted Sun
Rasterfile images.

2) Boundary errors within the XCF image decoder can be exploited to
cause a stack-based and a heap-based overflow when processing
specially crafted XCF image files.

Successful exploitation may allow execution of arbitrary code.

SOLUTION:
Update to version 6.2.9-1.

PROVIDED AND/OR DISCOVERED BY:
Tavis Ormandy, Google Security Team.
