-----BEGIN PGP SIGNED MESSAGE----- =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2003.0274 -- Apple Security Advisory Mac OS X 10.2.5 is now available 11 April 2003 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Mac OS X Vendor: Apple Operating System: Mac OS X Impact: Root Compromise Execute Arbitrary Code/Commands Denial of Service Access Required: Remote CVE Names: CAN-2003-0132, CAN-2003-0171, CAN-2003-0198, CAN-2003-0131, CAN-2003-0201, CAN-2003-0161 Ref: ESB-2003.0244 AL-2003.06 AL-2003.05 Comment: The Apple security bulletin below contains a bad PGP signature, however AusCERT has verified the contents as being valid. - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Mac OS X 10.2.5 is now available. It contains fixes for recent vulnerabilities in: Apache 2.0: Fixes CAN-2003-0132, a denial of service vulnerability in Apache 2.0 versions through 2.0.44. Apache 2.0 is distributed only with Mac OS X Server, and is not enabled by default. Directory Services: Fixes CAN-2003-0171 DirectoryServices Privilege Escalation and DoS Attack. DirectoryServices is part of the Mac OS X and Mac OS X Server information services subsystem. It is launched at startup, setuid root and installed by default. It is possible for a local attacker to modify an environment variable that would allow the execution of arbitrary commands as root. Credit to Dave G. from @stake, Inc. for the discovery of this vulnerability. File Sharing/Service: Fixes CAN-2003-0198 where the contents of the write-only DropBox folder can be revealed. When enabled, Personal File Sharing on Mac OS X or Apple File Service on Mac OS X Server, a "DropBox" folder is available by default to allow people to deposit files. This update no longer allows the permissions of the "DropBox" folder to be changed by a guest. OpenSSL: Fixes CAN-2003-0131 Klima-Pokorny-Rosa attack on PKCS #1 v1.5 padding. The patch from the OpenSSL team, which addresses this vulnerability, is applied to Mac OS X and Mac OS X Server. Samba: Fixes CAN-2003-0201 which could allow an anonymous user to gain remote root access due to a buffer overflow. The built-in Windows file sharing is based on the open source technology called Samba and is off by default in Mac OS X. sendmail: Fixes CAN-2003-0161, where address parsing code in sendmail does not adequately check the length of email addresses. Only the patch from the sendmail team is applied to the currently-shipping version of sendmail in Mac OS X and Mac OS X Server.
