Here's a collection of recent security vulnerabilities and alerts, which covers a new firmware update for the iPhone and iPod Touch, a new version of Miranda IM that fixes certain security issues, and a privilege escalation vulnerability in WinPcap.
- Apple closes TIFF hole in iPhone
Apple has released firmware update 1.1.2 for the iPhone and iPod Touch to remedy flaws discovered in the TIFF library. Once the update has been installed from iTunes though, manipulated TIFF files will no longer execute third-party software on the iPhone.
It is highly recommended for users who surf the Internet with their iPhone to install update 1.1.2 as soon as possible to prevent criminals from exploiting their units via manipulated websites or emails.

- New versions of Miranda released
Two new versions of Miranda, version 0.7.2 and 0.7.3 have been released. They close remote injection security holes that attackers could exploit remotely by means of manipulated messages and packets.
Version 0.7.2 remedied two buffer overflows in the modules that support MSN and Yahoo protocols. The security service provider Secunia had discovered the hole in the Yahoo module that allowed specially crafted authentication queries to exploit a format-string vulnerability in the function that adds Yahoo contacts to the contact list. For this vulnerability to be exploited, however, Miranda has to be connected to a manipulated server. The developers did not provide any further details concerning the flaw in the MSN module.

- WinPcap allows for privilege escalation
Security service provider iDefnese has warned of a vulnerability in the NPF.SYS device driver of WinPcap that could allow attackers to execute arbitrary code in kernel context. Applications such as Wireshark use this library to capture network packets.
The problem specifically exists within the bpf_filter_init function. In several places throughout this function, values supplied from a potential attacker are used as array indexes without proper bounds checking. By making IOCTL requests with specially chosen values, attackers are able to corrupt the stack, or pool memory, within the kernel.
This flaw affects WinPcap 4.0.1 and is fixed in WinPcap 4.0.2.
