TITLE

Apple Mac OS X Elevation of privilege vulnerability in Disk Utility

DESCRIPTION

The Repair Permissions tool in Disk Utility in Apple Mac OS X 10.4.11 adds the setuid bit to the emacs executable file, which allows local users to gain privileges by executing commands within emacs. Apple Mac OS X is prone to multiple security vulnerabilities that have been addressed in Security Update 2008-005. The security update addresses a total of six new vulnerabilities that affect the CarbonCore, CoreGraphics, Data Detectors Engine, Disk Utility, OpenLDAP, and QuickLook components of Mac OS X. The advisory also contains security updates for 11 previously reported issues. NOTE: This BID is being retired; the following individual records have been created to better document these issues: 30487 Apple Mac OS X CarbonCore Stack Based Buffer Overflow 30488 Apple Mac OS X CoreGraphics Multiple Memory Corruption Vulnerabilities 30489 Apple Mac OS X CoreGraphics Heap Based Buffer Overflow Vulnerability 30490 Apple Mac OS X Data Detectors Engine Denial Of Service Vulnerability 30492 Apple Mac OS X Disk Utility Privilege Escalation Vulnerability 30493 Apple Mac OS X QuickLook Multiple Memory Corruption Vulnerabilities. An unprivileged local user may exploit this issue to run commands with system-level privileges. The following versions are affected: Mac OS X v10.4.11 and prior Mac OS X Server v10.4.11 and prior This issue does not affect systems running Mac OS X v10.5 and later. 1) A vulnerability in BIND can be exploited to poison the DNS cache. For more information: SA30973 2) A boundary error exists in CarbonCore when handling filenames. This can be exploited to cause a stack-based buffer overflow via overly long filenames. Successful exploitation of the vulnerability may allow execution of arbitrary code. 3) Multiple errors exist in CoreGraphics when processing received arguments. These can be exploited to trigger a memory corruption by e.g. tricking a user into visiting a specially crafted website. Successful exploitation of the vulnerability may allow execution of arbitrary code. 4) An integer overflow error exists in CoreGraphics when handling PDF files. This can be exploited to cause a heap-based buffer overflow via a specially crafted PDF file. Successful exploitation of the vulnerability may allow execution of arbitrary code. 5) Multiple errors in QuickLook when downloading Microsoft Office files can be exploited to cause a memory corruption. Successful exploitation of the vulnerability may allow execution of arbitrary code. 6) An error exists in the Data Detectors engine when viewing a specially crafted message. This can be exploited to consume overly large resources and trigger an application using the engine to terminate. 7) The problem is that the "Repair Permissions" tool included in Disk Utility sets the "setuid" bit on "/usr/bin/emacs". This can be exploited to execute arbitrary commands with system privileges. 8) An error in OpenLDAP when parsing ASN.1 BER encoded packets can be exploited to cause a DoS. For more information: SA30853 9) A boundary error exists in the OpenSSL "SSL_get_shared_ciphers()" function. For more information see vulnerability #4 in: SA22130 10) Some vulnerabilities in PHP can be exploited malicious users to bypass certain security restrictions, and potentially by malicious people to cause a DoS (Denial of Service) or to compromise a vulnerable system. For more information: SA30048 11) Two vulnerabilities in rsync can be exploited by malicious users to bypass certain security restrictions.
