Apple rolls out 17 patches via security update

2007 isn't looking like a good year for Mac zealots who love to crow about how secure their platform of choice is: Apple just rolled out a security update last night, its fifth this year, containing patches for 17 potentially serious OS X bugs. That brings the grand total of OS X patches for 2007 up to a whopping 109. Among the fixes is a patch for a CoreGraphics bug that could allow a hacker to launch code execution attacks via a rigged PDF file. "By enticing a user to open a maliciously crafted PDF file, an attacker could trigger [a buffer] overflow which may lead to an unexpected application termination or arbitrary code execution," the company warned in a security advisory. Another serious buffer overflow flaw was found in the UPnP IGD (Internet Gateway Device Standardized Device Control Protocol) code used to create Port Mappings in iChat. "By sending a maliciously crafted packet, an attacker on the local network can trigger the overflow which may lead to an unexpected application termination or arbitrary code execution," Apple said.
