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.
