TITLE

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

DESCRIPTION

notifyd in Apple Mac OS X 10.4.11 does not verify that Mach port death notifications have originated from the kernel, which allows local users to cause a denial of service via spoofed death notifications that prevent other applications from receiving notifications. (DoS) There is a vulnerability that becomes a condition.Disguised disabling notifications by a malicious local user can prevent other applications from receiving notifications. Attackers can leverage this issue to cause denial-of-service conditions. These issues affect Mac OS X and various applications, including AFP Client, AFP Server, AppKit, Application Firewall, CoreFoundation, CoreServices, CUPS, Foundation, Help Viewer, Image Raw, libc, mDNSResponder, notifyd, pax archive utility, Podcast Producer, Preview, Printing, System Configuration, UDF, and Wiki Server. Attackers may exploit these issues to execute arbitrary code, trigger denial-of-service conditions, escalate privileges, and potentially compromise vulnerable computers. NOTE: This BID is being retired. The following individual records have been created to fully document all the vulnerabilities that were described in this BID: 28320 Apple Mac OS X AFP Client 'afp://' URI Remote Code Execution Vulnerability CVE-2008-0044. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. 1) Multiple boundary errors in AFP client when processing "afp://" URLs can be exploited to cause stack-based buffer overflows when a user connects to a malicious AFP server. Successful exploitation may allow execution of arbitrary code. 2) An error exists in AFP Server when checking Kerberos principal realm names. This can be exploited to make unauthorized connections to the server when cross-realm authentication with AFP Server is used. 3) Multiple vulnerabilities in Apache can be exploited by malicious people to conduct cross-site scripting attacks, cause a DoS (Denial of Service), or potentially compromise a vulnerable system. For more information: SA18008 SA21197 SA26636 SA27906 SA28046 4) A boundary error within the handling of file names in the NSDocument API in AppKit can be exploited to cause a stack-based buffer overflow. 6) Multiple integer overflow errors exist in the parser for a legacy serialization format. This can be exploited to cause a heap-based buffer overflow when a specially crafted serialized property list is parsed. Successful exploitation may allow execution of arbitrary code. 7) An error in CFNetwork can be exploited to spoof secure websites via 502 Bad Gateway errors from a malicious HTTPS proxy server. 8) Multiple vulnerabilities in ClamAV can be exploited by malicious people to cause a DoS (Denial of Service) or to compromise a vulnerable system. For more information: SA23347 SA24187 SA24891 SA26038 SA26530 SA28117 SA28907 9) An integer overflow error exists in CoreFoundation when handling time zone data. 10) The problem is that files with names ending in ".ief" can be automatically opened in AppleWorks if "Open 'Safe' files" is enabled in Safari. For more information: SA29431 12) Multiple input validation errors exist in CUPS, which can be exploited to execute arbitrary code with system privileges. 13) A boundary error in curl can be exploited to compromise a user's system. For more information: SA17907 14) A vulnerability in emacs can be exploited by malicious people to compromise a user's system. For more information: SA27508 15) A vulnerability in "file" can be exploited by malicious people to compromise a vulnerable system. For more information: SA24548 16) An input validation error exists in the NSSelectorFromString API, which can potentially be exploited to execute arbitrary code via a malformed selector name. 17) A race condition error in NSFileManager can potentially be exploited to gain escalated privileges. 18) A boundary error in NSFileManager can potentially be exploited to cause a stack-based buffer overflow via an overly long pathname with a specially crafted structure. 19) A race condition error exists in the cache management of NSURLConnection. This can be exploited to cause a DoS or execute arbitrary code in applications using the library (e.g. Safari). 20) A race condition error exists in NSXML. This can be exploited to execute arbitrary code by enticing a user to process an XML file in an application which uses NSXML. 21) An error in Help Viewer can be exploited to insert arbitrary HTML or JavaScript into the generated topic list page via a specially crafted "help:topic_list" URL and may redirect to a Help Viewer "help:runscript" link that runs Applescript. 22) A boundary error exists in Image Raw within the handling of Adobe Digital Negative (DNG) image files. This can be exploited to cause a stack-based buffer overflow by enticing a user to open a maliciously crafted image file. 23) Multiple vulnerabilities in Kerberos can be exploited to cause a DoS or to compromise a vulnerable system. For more information: SA29428 24) An off-by-one error the "strnstr()" in libc can be exploited to cause a DoS. 25) A format string error exists in mDNSResponderHelper, which can be exploited by a malicious, local user to cause a DoS or execute arbitrary code with privileges of mDNSResponderHelper by setting the local hostname to a specially crafted string. 27) An array indexing error in the pax command line tool can be exploited to execute arbitrary code. 28) Multiple vulnerabilities in php can be exploited to bypass certain security restrictions. For more information: SA27648 SA28318 29) A security issue is caused due to the Podcast Capture application providing passwords to a subtask through the arguments. 30) Printing and Preview handle PDF files with weak encryption. 31) An error in Printing in the handling of authenticated print queues can lead to credentials being saved to disk. 33) A null-pointer dereference error exists in the handling of Universal Disc Format (UDF) file systems, which can be exploited to cause a system shutdown by enticing a user to open a maliciously crafted disk image. 35) Some vulnerabilities in X11 can be exploited by malicious, local users to gain escalated privileges. For more information: SA27040 SA28532 36) Some vulnerabilities in libpng can be exploited by malicious people to cause a DoS (Denial of Service).
