libxml2 before 2.7.8, as used in Google Chrome before 7.0.517.44, Apple Safari 5.0.2 and earlier, and other products, reads from invalid memory locations during processing of malformed XPath expressions, which allows context-dependent attackers to cause a denial of service (application crash) via a crafted XML document.

Buffer overflow in Apple iTunes before 9.2.1 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted itpc: URL.

Buffer overflow in pngpread.c in libpng before 1.2.44 and 1.4.x before 1.4.3, as used in progressive applications, might allow remote attackers to execute arbitrary code via a PNG image that triggers an additional data row.

Memory leak in pngrutil.c in libpng before 1.2.44, and 1.4.x before 1.4.3, allows remote attackers to cause a denial of service (memory consumption and application crash) via a PNG image containing malformed Physical Scale (aka sCAL) chunks.

WebKit in Apple iTunes before 9.2 on Windows, and Apple iOS before 4 on the iPhone and iPod touch, accesses out-of-bounds memory during the handling of tables, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted HTML document, a different vulnerability than CVE-2010-1387 and CVE-2010-1763.

Unspecified vulnerability in WebKit in Apple iTunes before 9.2 on Windows has unknown impact and attack vectors, a different vulnerability than CVE-2010-1387 and CVE-2010-1769.
