Unspecified vulnerability in Safari 4 on Apple Mac OS X 10.6 allows remote attackers to execute arbitrary code via unknown vectors, as demonstrated by Charlie Miller during a Pwn2Own competition at CanSecWest 2010. Vulnerabilidad sin especificar en Safari 4 sobre Apple Mac Os X v10.6, permite a atacantes remotos ejecutar código de su elección a través de vectores desconocidos, como ha demostrado Charlie Miller durante la competición Pwn2Own en CanSecWest 2010. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Preview. User interaction is required in that a target must open a malicious file or visit a malicious page. The specific flaw exists within the routine TType1ParsingContext::SpecialEncoding() defined in libFontParser.dylib. While parsing glyphs from a PDF document, a malformed offset greater than 0x400 can result in a heap corruption which can be leveraged by an attacker to execute arbitrary code under the context of the current user. • http://dvlabs.tippingpoint.com/blog/2010/02/15/pwn2own-2010 http://news.cnet.com/8301-27080_3-20001126-245.html http://twitter.com/thezdi/statuses/11002504493 • CWE-94: Improper Control of Generation of Code ('Code Injection') •

Use-after-free vulnerability in WebKit in Apple Safari before 4.0.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via HTML elements with right-to-left (RTL) text directionality. Vulnerabilidad de uso después de liberacion en WebKit de Apple Safari en versiones anteriores a la v4.0.5 permite a usuarios remotos ejecutar comandos de su elección o provocar una denegación de servicio (caida de la aplicación) a través de elementos HTML con direccionalidad de texto de derecha a izquierda (RTL). This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple's Webkit. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists due to the method by which the Webkit library renders right-to-left text. If a linebox has a width greater than it's container, Webkit frees an object that upon page destruction is freed again. • https://www.exploit-db.com/exploits/33752 http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=863 http://lists.apple.com/archives/security-announce/2010/Jun/msg00003.html http://lists.apple.com/archives/security-announce/2010/Mar/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041383.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041432.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041436.html http:/&# • CWE-399: Resource Management Errors •

Use-after-free vulnerability in WebKit in Apple Safari before 4.0.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to the run-in Cascading Style Sheets (CSS) display property. Vulnerabilidad de uso después de la liberación en WebKit de Apple Safari anterior a la v4.0.5, permite a atacantes remotos ejecutar código de su elección o provocar una denegación de servicio (caída de la aplicación) a través de vectores relacionados con la propiedad de run-in de visualizar las Hojas de Estilo en Cascada -Cascading Style Sheets, CSS- This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari and other WebKit based browsers. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists in the handling of the run-in value for display CSS styles. A specially crafted web page can cause a use after free() condition in WebKit's WebCore::RenderBlock() method. This can be further leveraged by attackers to execute arbitrary code under the context of the current user. • http://lists.apple.com/archives/security-announce/2010/Jun/msg00003.html http://lists.apple.com/archives/security-announce/2010/Mar/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041383.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041432.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041436.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http://osvdb.org/62948 http://secunia.com/a • CWE-399: Resource Management Errors •
