TITLE

Apple Mac OS X Man-in-the-middle attack arbitrary command execution vulnerability

DESCRIPTION

Software Update in Apple Mac OS X 10.5.1 allows remote attackers to execute arbitrary commands via a man-in-the-middle (MITM) attack between the client and the server, using a modified distribution definition file with the "allow-external-scripts" option. Successfully exploiting this issue in conjunction with other latent vulnerabilities may allow an attacker to execute arbitrary commands on affected computers, provided that the 'allow-external-scripts' option is enabled. There are loopholes in the implementation of the OS X software upgrade mechanism, and remote attackers may control the user system through fake upgrade sites. The OS X software upgrade mechanism uses "release packages", which consist of two main parts: an XML catalog file listing available upgrades; and a "release definition file" that contains XML and JavaScript-encoded information that defines what to expect when an upgrade is installed. content in all aspects. When OS X checks for new updates, it first contacts swscan.apple.com to receive an XML catalog file that references distribution definition files that may be located on other servers. After the software upgrade receives these files, it calls some other JavaScript function to check whether the update is suitable for the local machine. The above-mentioned files are transmitted through HTTP without any authentication. I. Further details are available in the related vulnerability notes. The update addresses vulnerabilities in other vendors' products that ship with Apple OS X or OS X Server. These products include: * Adobe Flash * Adobe Shockwave * GNU Tar II. Impact The impacts of these vulnerabilities vary. Potential consequences include arbitrary code execution, sensitive information disclosure, surreptitious video conference initiation, and denial of service. III. This and other updates are available via Software Update or via Apple Downloads. IV.

Successful exploitation may allow execution of arbitrary code. 4) A race condition exists in the "CFURLWriteDataAndPropertiesToResource" API, which can lead to files being created with insecure permissions. 5) A boundary error exists in the printer driver for CUPS. This can be exploited to cause a buffer overflow and allows an admin user to execute arbitrary code with system privileges by passing a specially crafted URI to the CUPS service. 6) A boundary error in CUPS can be exploited by malicious people to compromise a vulnerable system. For more information: SA27233 7) An integer underflow error in the CUPS backend in the handling of SNMP responses can be exploited to cause a stack-based buffer overflow by sending a specially crafted SNMP response. Successful exploitation allows execution of arbitrary code, but requires that SNMP is enabled. 8) A boundary error in Desktop Services can be exploited to cause a heap-based buffer overflow when a user opens a directory containing a specially crafted .DS_Store file. Successful exploitation may allow execution of arbitrary code. 9) An input validation error in tar can be exploited by malicious people to compromise a user's system. For more information: SA26573 10) An unspecified error in iChat can be exploited by malicious people on the local network to initiate a video connection without the user's approval. 11) An unspecified error exists within IO Storage Family when handling GUID partition maps within a disk image. This can be exploited to execute arbitrary code when a user is enticed to open a specially crafted disk image. 12) Launch Services does not handle HTML files as potentially unsafe content. This can be exploited to disclose sensitive information or conduct cross-site scripting attacks by enticing a user to open a specially crafted HTML file. 13) A vulnerability in Mail in the handling of unsafe file types can be exploited to compromise a user's system. For more information: SA27785 14) An error in Mail can cause the application to default to SMTP plaintext authentication if the server supports only MD5 Challenge-Response authentication and plaintext authentication. 15) Some vulnerabilities in perl can be exploited by malicious people to compromise a vulnerable system. For more information: SA27546 16) A security issue in python can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system. For more information: SA26837 17) Plug-ins in Quick Look are not restricted from making network requests. This may lead to the disclosure of sensitive information when previewing an HTML file. 18) URLs contained in movie files may be accessed when creating an icon for a movie file or previewing a movie file using QuickLook. 19) Some security issues in ruby can be exploited by malicious people to conduct spoofing attacks. For more information: SA26985 20) Some vulnerabilities and a security issue in Ruby on Rails can be exploited by malicious people to disclose sensitive information or to conduct session fixation attacks. For more information: SA25699 SA27781 21) An error in Safari allows a page to navigate the subframes of any other page. This can be exploited to conduct cross-site scripting attacks and to disclose sensitive information when a user visits a specially crafted web page. 22) An unspecified error in Safari in the handling of RSS feeds can be exploited to cause a memory corruption and may allow execution of arbitrary code when a user accesses a specially crafted URL. 23) Some boundary errors in Samba can be exploited by malicious people to compromise a vulnerable system. For more information: SA27450 24) Some boundary errors in the Shockwave Plug-in can be exploited by malicious people to compromise a user's system. For more information: SA19218 25) A boundary error in the processing of command line arguments to "mount_smbfs" and "smbutil" can be exploited to cause a stack-based buffer overflow and execute arbitrary code with system privileges. Successful exploitation requires a MitM (Man-in-the-Middle) attack. 27) An error due to an insecure file operation exists in the handling of output files in SpinTracer. This may allow a malicious, local user to execute arbitrary code with system privileges. 28) An unspecified error exists in the Microsoft Office Spotlight Importer, which can be exploited to cause a memory corruption when a user downloads a specially crafted .xls file. Successful exploitation may allow execution of arbitrary code. 29) Some vulnerabilities in tcpdump can be exploited by malicious people to cause a DoS or to compromise a user's system. For more information: SA24318 SA26135 30) Some vulnerabilities exist the Perl Compatible Regular Expressions (PCRE) library used by XQuery, which can potentially be exploited to compromise a vulnerable system.
