CVE-2006-1988

TITLE

Apple Mac OS X Multiple heap overflow vulnerabilities

DESCRIPTION

The WebTextRenderer(WebInternal) _CG_drawRun:style:geometry: function in Apple Safari 2.0.3 allows remote attackers to cause a denial of service (application crash) via an HTML LI tag with a large VALUE attribute (list item number), which triggers a null dereference in QPainter::drawText, probably due to a failed memory allocation that uses the VALUE. Apple Mac OS X is reported prone to multiple security vulnerabilities. These issue affect Mac OS X and various applications including Safari, Preview, Finder, QuickTime, and BOMArchiveHelper. A remote attacker may exploit these issues to execute arbitrary code and/or trigger a denial-of-service condition. Apple Mac OS X 10.4.6 and prior are reported vulnerable to these issues. When parsing malformed .tiff graphic files, LZWDecodeVector(), _cg_TIFFSetField () or PredictorVSetField () functions do not correctly parse the malformed data, resulting in the failure to open the graphic Application crashes. The vulnerability is triggered by the core .tiff parsing engine, so Preview, Finder, QuickTime, and Safari are all possible attack vectors. 2 When decompressing a specially crafted .zip file, the BOMStackPop () function does not correctly parse the malformed data, resulting in a heap overflow vulnerability. 4 When decompressing a specially crafted .bmp file, the ReadBMP () function does not correctly parse the malformed data, resulting in a heap overflow vulnerability. 5 When decompressing a specially crafted .gif file, the CFAllocatorAllocate () function does not correctly parse the malformed data, resulting in a heap overflow vulnerability. 1) An error exists in the "BOMStackPop()" function in the BOMArchiveHelper when decompressing malformed ZIP archives. 2) Some errors exists in the "KWQListIteratorImpl()", "drawText()", and "objc_msgSend_rtp()" functions in Safari when processing malformed HTML tags. 3) An error exists in the "ReadBMP()" function when processing malformed BMP images and can be exploited via e.g. Safari or the Preview application. 4) An error exists in the "CFAllocatorAllocate()" function when processing malformed GIF images and can be exploited via e.g. Safari when a user visits a malicious web site. 5) Two errors exists in the " _cg_TIFFSetField ()" and "PredictorVSetField()" functions when processing malformed TIFF images and can be exploited via e.g. The vulnerabilities have been reported in version 10.4.6. Other versions may also be affected. SOLUTION: Do not visit untrusted web sites, and do not open ZIP archives or images originating from untrusted sources.
