TITLE

Apple Mac OS X of Podcast Producer Elevation of privilege vulnerability

DESCRIPTION

Podcast Producer in Apple Mac OS X 10.5 before 10.5.6 allows remote attackers to bypass authentication and gain administrative access via unspecified vectors. Apple Mac OS X is prone to multiple security vulnerabilities that have been addressed in Security Update 2008-008. The advisory also contains security updates for 10 previously reported issues. This BID is being retired. The following individual records have been created to better document the issues: 32870 Apple Podcast Producer Authentication-Bypass Vulnerability 32872 Apple Mac OS X UDF ISO File Handling Denial of Service Vulnerability 32873 Apple Mac OS X NFS Mounted Executable Exception Remote Denial of Service Vulnerability 32874 Apple Mac OS X 'natd' Remote Denial of Service Vulnerability 32875 Apple Mac OS X Type Services PDF File Remote Denial of Service Vulnerability 32876 Apple Mac OS X BOM CPIO Header Stack Buffer Overflow Vulnerability 32877 Apple Mac OS X 'inet_net_pton' API Integer Overflow Vulnerability 32879 Apple Mac OS X 'i386_set_ldt' and '1386_get_ldt' Multiple Integer Overflow Vulnerabilities 32880 Apple Mac OS X Managed Client Screen Saver Lock Bypass Vulnerability 32881 Apple Mac OS X 'strptime' API Memory Corruption Vulnerability. Podcast Producer is prone to an authentication-bypass vulnerability. An attacker can exploit this issue to gain access to certain administrative functions. This may result in an elevation of privilege and may aid in further attacks. This issue affects Podcast Producer for Mac OS X Server 10.5 through 10.5.5. 1) An infinite loop when processing certain embedded fonts in PDF files within the Apple Type Services server can be exploited to cause a DoS (Denial of Service) by e.g. tricking a user into opening a malicious PDF file. 2) A signedness error when handling certain CPIO archive headers exists within BOM. This can be exploited to execute arbitrary code by e.g. downloading or viewing a specially crafted CPIO archive. 3) An error within the processing of color spaces within CoreGraphics can be exploited to cause a heap-based buffer overflow by e.g. tricking a user into viewing a specially crafted image. Successful exploitation may allow the execution of arbitrary code. 4) Some security issues and vulnerabilities have been reported in Adobe Flash Player, which can be exploited by malicious people to bypass certain security restrictions, manipulate certain data, conduct cross-site scripting attacks, or disclose sensitive information. For more information: SA32270 5) Multiple integer overflows exist within the "i386_set_ldt()" and "i386_get_ldt()" system calls, which can be exploited by malicious, local users to execute arbitrary code with system privileges. Note: This does not affect PowerPC systems. 6) An infinite loop when handling exceptions in an application linked to libraries on an NFS share can be exploited to cause a system shutdown. 7) An integer overflow error exists in the "inet_net_pton()" API of Libsystem. This can potentially be exploited to e.g. compromise an application using the vulnerable function. 8) An unspecified error when processing certain input within the "strptime()" API of Libsystem can be exploited to cause a memory corruption and potentially execute arbitrary code by e.g. passing a specially crafted date string to an application using the vulnerable function. 9) The "Managed Client" functionality does not always apply the managed screen saver settings correctly, potentially resulting in e.g. the screen saver lock not working as intended. 10) An infinite loop when processing certain TCP packets exists in natd, which can be exploited to cause a DoS by sending specially crafted TCP packets to a vulnerable system. Successful exploitation requires that Internet Sharing is enabled. 12) An unspecified error within the handling of malformed UDF volumes can be exploited to cause a system shutdown by e.g. opening a specially crafted ISO file. Additionally, this update enhances the CoreTypes "Download Validation" capability to detect and warn about more potentially dangerous file types. http://www.apple.com/support/downloads/ PROVIDED AND/OR DISCOVERED BY: 1) The vendor credits Michael Samarin and Mikko Vihonen, Futurice Ltd 2, 3, 8) Reported by the vendor. 5) The vendor credits Richard Vaneeden, IOActive, Inc 6) The vendor credits Ben Loer, Princeton University 9) The vendor credits John Barnes of ESRI and Trevor Lalish-Menagh of Tamman Technologies, Inc 10) The vendor credits Alex Rosenberg of Ohmantics and Gary Teter of Paizo Publishing 12) The vendor credits Mauro Notarianni of PCAX Solutions ORIGINAL ADVISORY: http://support.apple.com/kb/HT3338 OTHER REFERENCES: SA32270: http://secunia.com/advisories/32270/ ---------------------------------------------------------------------- About: This Advisory was delivered by Secunia as a free service to help everybody keeping their systems up to date against the latest vulnerabilities.
