Description
Apple has issued a security update for Mac OS X, which fixes multiple vulnerabilities.
1) A divide-by-zero error in AirPort when handling Wi-Fi frames can be exploited to cause a system reset.
2) Multiple vulnerabilities in Apache can be exploited by malicious people to disclose potentially sensitive information and by malicious users and malicious people to cause a DoS (Denial of Service).
For more information:
3) A format string error within AppleScript Studio when handling certain commands via dialogs can be exploited to potentially execute arbitrary code.
4) An unspecified error in the handling of embedded OpenType fonts in Apple Type Services (ATS) can be exploited to cause a heap-based buffer overflow when a specially crafted document is viewed or downloaded.
5) Multiple unspecified errors in the handling of embedded TrueType fonts in Apple Type Services (ATS) can be exploited to cause a buffer overflow when a specially crafted document is viewed or downloaded.
6) Multiple unspecified errors in the handling of embedded Type 1 fonts in Apple Type Services (ATS) can be exploited to cause a buffer overflow when a specially crafted document is viewed or downloaded.
7) Multiple unspecified errors in the handling of SFNT tables in embedded fonts in Apple Type Services (ATS) can be exploited to cause a buffer overflow when a specially crafted document is viewed or downloaded.
8) An integer overflow error in bzip2 can be exploited to terminate an application using the library or execute arbitrary code via a specially crafted archive.

12) An integer overflow error within the handling of the F_READBOOTSTRAP ioctl in HFS, HFS+, and HFS+J filesystems can be exploited to read arbitrary files.
13) An error in ImageIO within the handling of JPEG files can be exploited to cause a heap-based buffer overflow.
14) An integer overflow error in ImageIO within the handling of XBM files can be exploited to potentially execute arbitrary code.
15) An error in libTIFF within the handling of JPEG encoded TIFF files can be exploited to cause a buffer overflow.
16) An error in libTIFF within the handling of CCITT Group 4 encoded TIFF files can be exploited to cause a buffer overflow.
17) An integer overflow error in ImageIO within the handling of JPEG encoded TIFF files can be exploited to potentially execute arbitrary code.
18) Multiple errors in Image RAW when handling Canon RAW image files can be exploited to cause buffer overflows.
19) An error in the Install Helper when handling URLs can be exploited to install an arbitrary agent by tricking the user into visiting a malicious website.
20) Multiple errors in Kerberos can be exploited by malicious users and malicious people to conduct spoofing attacks and bypass certain security features.
21) An error within the "i386_set_ldt ()" system call can be exploited by malicious, local users to execute arbitrary code with system privileges.
22) An integer truncation error within Libinfo when handling NFS RPC packets can be exploited to cause NFS RPC services to become unresponsive.
23) An error exists in the libxml library when traversing the XPath.
