CVE-2007-6359

TITLE

Apple Mac OS X of cs_validate_page Service disruption in functions (DoS) Vulnerabilities

DESCRIPTION

The cs_validate_page function in bsd/kern/ubc_subr.c in the xnu kernel 1228.0 and earlier in Apple Mac OS X 10.5.1 allows local users to cause a denial of service (failed assertion and system crash) via a crafted signed Mach-O binary that causes the hashes function to return NULL. Mac OS X is prone to a denial-of-service vulnerability. I. Further details are available in the US-CERT Vulnerability Notes Database. II. III. These and other updates are available via Software Update or via Apple Downloads. IV. Please send email to <cert@cert.org> with "TA08-150A Feedback VU#566875" in the subject. _________________________________________________________________ For instructions on subscribing to or unsubscribing from this mailing list, visit <http://www.us-cert.gov/cas/signup.html>. _________________________________________________________________ Produced 2008 by US-CERT, a government organization.

These can be exploited to cause memory corruption and potentially allow for execution of arbitrary code when a user opens a specially crafted movie file. 5) An unspecified error exists in Apple Type Services when processing embedded fonts in PDF files. This can be exploited to cause a memory corruption when a PDF file containing a specially crafted embedded font is printed. Successful exploitation may allow execution of arbitrary code. 6) An error in Safari's SSL client certificate handling can lead to an information disclosure of the first client certificate found in the keychain when a web server issues a client certificate request. 7) An integer overflow exists in CoreFoundation when handling CFData objects. This can be exploited to cause a heap-based buffer overflow if an application calls "CFDataReplaceBytes" with an invalid "length" argument. 8) An error due to an uninitialised variable in CoreGraphics can potentially be exploited to execute arbitrary code when a specially crafted PDF is opened. 9) A weakness is caused due to users not being warned before opening certain potentially unsafe content types. 10) An error when printing to password-protected printers with debug logging enabled may lead to the disclosure of sensitive information. 11) Some vulnerabilities in Adobe Flash Player can be exploited by malicious people to bypass certain security restrictions, conduct cross-site scripting attacks, or to potentially compromise a user's system. For more information: SA28083 12) An integer underflow error in Help Viewer when handling help:topic URLs can be exploited to cause a buffer overflow when a specially crafted help:topic URL is accessed. Successful exploitation may allow execution of arbitrary code. 13) A conversion error exists in ICU when handling certain character encodings. This can potentially be exploited bypass content filters and may lead to cross-site scripting and disclosure of sensitive information. 14) Input passed to unspecified parameters in Image Capture's embedded web server is not properly sanitised before being used. This can be exploited to disclose the content of local files via directory traversal attacks. 15) An error in the handling of temporary files in Image Capture can be exploited by malicious, local users to manipulate files with the privilege of a user running Image Capture. 16) A boundary error in the BMP and GIF image decoding engine in ImageIO can be exploited to disclose content in memory. 17) Some vulnerabilities in ImageIO can be exploited by malicious people to cause a DoS (Denial of Service). The vulnerabilities are caused due to the use of vulnerable libpng code. For more information: SA27093 SA27130 18) An integer overflow error in ImageIO within the processing of JPEG2000 images can be exploited to cause a heap-based buffer overflow when a specially crafted JPEG2000 image is viewed. Successful exploitation of this vulnerability may allow execution of arbitrary code. 19) An error in Mail is caused due to an uninitialised variable and can lead to disclosure of sensitive information and potentially execution of arbitrary code when mail is sent through an SMTP server over IPv6. 20) A vulnerability in Mongrel can be exploited by malicious people to disclose sensitive information. For more information: SA28323 21) The sso_util command-line tool requires that passwords be passed to it in its arguments, which can be exploited by malicious, local users to disclose the passwords. 22) An error in Wiki Server can be exploited to determine valid local user names when nonexistent blogs are accessed.
