TITLE

Apple Mac OS of Folder Manager Vulnerable to reading the "Download" folder

DESCRIPTION

Folder Manager in Apple Mac OS X 10.5.6 uses insecure default permissions when recreating a Downloads folder after it has been deleted, which allows local users to bypass intended access restrictions and read the Downloads folder. The security update addresses new vulnerabilities that affect the AFP server, movie playing, Resource Manager, Certificate Assistant, CoreText, 'dscl', Folder Manager, FSEvents, csregprinter, Remote Apple Event Viewer, Safari, Xterm, and SMB components of Mac OS X. The advisory also contains security updates for 32 previously reported issues. Apple Mac OS X is prone to a local information-disclosure vulnerability. A local attacker may exploit this issue to gain access to the Downloads folders of other users and potentially obtain sensitive information. This may aid in further attacks. This issue affects Mac OS X v10.5.6 and Mac OS X Server v10.5.6. NOTE: This issue was previously covered in BID 33759 (Apple Mac OS X 2009-001 Multiple Security Vulnerabilities), but has been assigned its own record to better document it. 1) A race condition error in the AFP Server can be exploited to trigger the execution of an infinite loop by sending a specially crafted file enumeration request. 2) An error in the handling of movie files using the Pixlet codec can be exploited to trigger a memory corruption. 3) An error in the Resource Manager related to CarbonCore can be exploited to trigger a memory corruption via a file containing a specially crafted resource fork. Successful exploitation of vulnerabilities #2 and #3 may allow execution of arbitrary code. 4) Certificate Assistant handles temporary files in an insecure manner. This can be exploited to overwrite arbitrary files with the privileges of the user running the application. 5) Two errors in ClamAV can be exploited to cause a crash or potentially execute arbitrary code. For more information: SA32663 SA32926 6) An error in CoreText when processing specially crafted Unicode strings can be exploited to cause a heap-based buffer overflow via e.g. a specially crafted web page. Successful exploitation of this vulnerability may allow execution of arbitrary code. 7) The dscl program accepts passwords passed via command line arguments. This can be exploited by local users to obtain the received passwords via the process list. 8) Multiple errors in fetchmail can be exploited by malicious people to cause a crash via overly large e-mail headers. 10) An error in the fseventsd program can be exploited to disclose normally restricted filesystem activity via the FSEvents framework. 11) An error in perl when processing Unicode characters can be exploited to trigger a memory corruption and potentially execute arbitrary code. This is related to: SA27546 12) An error handling problem in csregprinter can be exploited to cause a heap-based buffer overflow and potentially gain system privileges. 13) Multiple errors in python have an unknown impact or can be exploited to cause a crash or potentially compromise a vulnerable system. For more information: SA26837 SA31305 14) An uninitialized memory access error in the Remote Apple events server can be exploited to disclose potentially sensitive memory contents via specially crafted Remote Apple events. 15) An error in Server Manager while validating authentication credentials can be exploited to alter the system configuration. 16) An integer overflow in the SMB implementation can be exploited to cause a heap-based buffer overflow by tricking a user into connecting to a malicious SMB server. Successful exploitation of this vulnerability may allow execution of arbitrary code. 17) An error in the SMB implementation can be exploited to exhaust available memory resources and cause a system shutdown by tricking a user into connecting to a malicious SMB server. 18) An error in SquirrelMail can be exploited to inject and execute arbitrary HTML and script code via a specially crafted email. For more information: SA30627 20) Multiple errors in FreeType can be exploited to cause a DoS or compromise an application using the library. For more information: SA24741 22) Xterm creates TTY devices accessible to all users, when used with "luit". This can be exploited to e.g. write data to another user's Xterm.
