TITLE

Apple Mac OS of Launch Services Vulnerable to arbitrary code execution

DESCRIPTION

Incomplete blacklist vulnerability in Launch Services in Apple Mac OS X 10.5.8 allows user-assisted remote attackers to execute arbitrary code via a .fileloc file, which does not trigger a "potentially unsafe" warning message in the Quarantine feature. Apple Mac OS X is prone to a vulnerability that may allow attackers to bypass certain security warnings. The issue affects the Launch Services component. Successfully exploiting this issue may allow attackers to bypass certain security warnings and trick a user into opening unsafe malicious files. The following versions are affected: Mac OS X 10.5.8 and prior Mac OS X Server 10.5.8 and prior NOTE: This issue was previously covered in BID 36349 (Apple Mac OS X 2009-005 Multiple Security Vulnerabilities), but has been assigned its own record to better document it. This update adds the .fileloc type to the category of content types that the system flags as unsafe in certain circumstances (such as when downloading from mail). Although this content type is not automatically opened, it may execute malicious payloads if opened manually. ---------------------------------------------------------------------- Do you have VARM strategy implemented? (Vulnerability Assessment Remediation Management) If not, then implement it through the most reliable vulnerability intelligence source on the market. Implement it through Secunia. 1) An error in Alias Manager when processing alias files can be exploited to cause a buffer overflow and potentially execute arbitrary code. 2) An error in Resource Manager when processing resource forks can be exploited to corrupt memory and potentially execute arbitrary code. 3) Multiple vulnerabilities in ClamAV can be exploited to bypass certain security restrictions, cause a DoS, and potentially compromise a vulnerable system. For more information: SA34566 SA34612 4) An integer overflow error exists when processing ColorSync profiles embedded in images. This can be exploited to cause a heap-based buffer overflow and potentially execute arbitrary code via a specially crafted image. 5) An integer overflow error exists in CoreGraphics when processing JBIG2 streams embedded in PDF files. This can be exploited to cause a heap-based buffer overflow and potentially execute arbitrary code via a specially crafted PDF file. 6) An error in CoreGraphics can be exploited to cause a heap-based buffer overflow potentially execute arbitrary code when drawing long text strings. This is related to vulnerability #1 in: SA36269 7) A NULL-pointer dereference error in CUPS can be exploited to cause a crash. For more information see vulnerability #4 in: SA34481 8) An error in the CUPS USB backend can be exploited to cause a heap-based buffer overflow and execute arbitrary code with escalated privileges. 9) Multiple vulnerabilities in Adobe Flash Player can be exploited by malicious people to bypass security features, gain knowledge of sensitive information, or compromise a user's system. For more information: SA35948 10) Multiple errors exist in ImageIO when processing PixarFilm encoded TIFF images. These can be exploited to trigger memory corruptions and potentially execute arbitrary code via specially crafted TIFF files. 11) An error exists in Launch Services when handling files having a ".fileloc" extension. 12) An error exists in Launch Services when handling exported document types presented when an application is downloaded. This can be exploited to associate a safe file extension with an unsafe Uniform Type Identifier (UTI) and execute arbitrary code. For more information: SA30134 14) Multiple vulnerabilities in PHP have an unknown impact or can potentially be exploited by malicious people to disclose sensitive information or cause a DoS (Denial of Service). For more information: SA34081 15) An error exists in Samba when handling error conditions. This can be exploited by a user without a configured home directory to access the contents of the file system by connecting to the Windows File Sharing service. 16) Input passed in search requests containing non UTF-8 encoded data to Wiki Server is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
