TITLE

Apple Mac OS X MallocStackLogging Local Arbitrary File Modification Vulnerability

DESCRIPTION

The malloc function in the libSystem library in Apple Mac OS X 10.3.9 and 10.4.2 allows local users to overwrite arbitrary files by setting the MallocLogFile environment variable to the target file before running a setuid application. Ruby includes a vulnerable default value that may be used to bypass security restrictions and execute arbitrary code. Apple Mac OS X QuickDraw Manager contains a buffer overflow that may allow a remote attacker to execute arbitrary code. Two vulnerabilities in Mail resulting in information disclosure. A local privilege escalation vulnerability in malloc. This issue has been split into BID 14939. An arbitrary code execution vulnerability in QuickDraw Manager. A privilege escalation vulnerability in QuickTime for Java. A cross-site scripting vulnerability in Safari. An unauthorized access vulnerability in SecurityAgent. A privilege escalation vulnerability in securityd. This issue is due to insecure file handling in the 'malloc()' library for setuid applications. This issue occurs due to insufficient checks in the memory allocation library, leading to local users being able to utilize the debugging features on setuid applications. A local attacker could exploit this vulnerability to create, or append data to arbitrary files with superuser privileges. Depending on the purpose of the modified files, this may cause system crashes, or allow attackers to gain elevated privileges. 1) A boundary error in ImageIO can be exploited to cause a buffer overflow and may allow execution of arbitrary code on a user's system when a specially crafted GIF file is opened e.g. in WebCore or Safari. 2) An error in Mail.app when processing auto-reply rules can cause an automatically generated response message to include a plain-text copy of the encrypted message. This may disclose certain sensitive information. 3) An error in Mail.app when using Kerberos 5 for SMTP authentication can cause un-initialized memory to be appended to a message. This may disclose certain sensitive information. For more information: SA16449 4) "malloc" creates diagnostic files insecurely when certain environmental variables are set to enable debugging of application memory allocation. from Safari, Mail, or Finder. 6) A validation error in the Java extensions bundled with QuickTime 6.52 and earlier can be exploited by untrusted applets to call arbitrary functions from system libraries. For more information: SA15767 8) A validation error in Safari when rendering web archives from a malicious site can be exploited to execute arbitrary HTML and script code in a user's browser session in the context of another site. For more information: SA16449 9) An error in the SecurityAgent may cause the "Switch User..." button to be displayed even when the "Enable fast user switching" setting has been disabled. This may allow malicious, local users to access the current user's desktop without authentication even when the "Require password to wake this computer from sleep or screen saver" setting is enabled. 10) A validation error in the Authorization Services "securityd" allows unprivileged users to gain certain privileges that should be restricted to administrative users. This can be exploited by malicious, local users to gain escalated privileges. SOLUTION: Apply Security Update 2005-008.

The vulnerability is caused due to an unspecified error in the XMLRPC module, which may be exploited to execute arbitrary commands on a vulnerable XMLRPC server. The vulnerability has been reported in version 1.8.2. Prior versions may also be affected. SOLUTION: The vulnerability has been fixed in the CVS repository
