---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German. The improvements will help our customers to get a better understanding of how we reached our conclusions, how it was rated, our thoughts on exploitation, attack vectors, and scenarios. This includes: * Reason for rating * Extended description * Extended solution * Exploit code or links to exploit code * Deep links Read the full description: http://corporate.secunia.com/products/48/?r=l Contact Secunia Sales for more information: http://corporate.secunia.com/how_to_buy/15/?r=l ---------------------------------------------------------------------- TITLE: Mac OS X Security Update Fixes Multiple Vulnerabilities SECUNIA ADVISORY ID: SA23155 VERIFY ADVISORY: http://secunia.com/advisories/23155/ CRITICAL: Highly critical IMPACT: Security Bypass, Manipulation of data, Exposure of sensitive information, Privilege escalation, DoS, System access WHERE: >From remote OPERATING SYSTEM: Apple Macintosh OS X http://secunia.com/product/96/ DESCRIPTION: Apple has issued a security update for Mac OS X, which fixes multiple vulnerabilities. 1) An error in the Airport driver can be exploited by malicious people to compromise a vulnerable system. For more information: SA22679 2) The Apple Type Services (ATS) server creates error log files insecurely. This can be exploited by malicious, local users to create or overwrite files with system privileges. 3) Multiple boundary errors in the Apple Type Services (ATS) server can be exploited by malicious, local users to cause a buffer overflow and execute arbitrary code with system privileges by sending a specially crafted request. 4) A boundary error in Apple Type Services (ATS) can be exploited to cause a stack-based buffer overflow via specially crafted font files and allows execution of arbitrary code with system privileges. 5) An error in the CFNetwork framework can be exploited to cause a user's FTP client to issue arbitrary FTP commands when a user accesses a specially crafted FTP URI. This may facilitate exploitation via other line oriented protocols. 6) Vulnerabilities in ClamAV can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system. For more information: SA22370 7) A boundary error in Finder can be exploited to cause a heap-based buffer overflow and may allow arbitrary code execution when a user browses a directory containing a specially crafted ".DS_Store" file. 8) An error in the ftpd can be exploited by malicious people to determine valid account names and to cause a DoS (Denial of Service) via failed login attempts with a valid username. 9) Some vulnerabilities in gnuzip can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system. For more information: SA21996 10) Some vulnerabilities in OpenSSL can be exploited by malicious people to cause a DoS (Denial of Service), bypass certain security restrictions, or compromise a vulnerable system. For more information: SA21709 SA22130 11) A vulnerability in Perl can be exploited by malicious people to cause a Denial of Service and potentially to compromise a vulnerable Perl application. For more information: SA17802 12) Some vulnerabilities in PHP can be exploited by malicious people to gain knowledge of potentially sensitive information, to cause a DoS (Denial of Service), or to compromise a vulnerable system. For more information: SA19383 SA19803 SA22653 13) A boundary error in PPP can be exploited to cause a buffer overflow. This can be exploited to cause a DoS (Denial of Service) or execute arbitrary code with system privileges. 14) A vulnerability in Samba can be exploited by malicious users to cause a DoS (Denial of Service). For more information: SA20980 15) A security issue in the Security Framework has been fixed where Secure Transport may not negotiate the best cipher available. 16) An error in the Security Framework when processing X.509 certificates can be exploited to cause a DoS (Denial of Service). NOTE: Systems prior to Mac OS X v10.4 are not affected. 17) A security issue in the Security Framework has been fixed where the Online Certificate Status Protocol (OCSP) service cannot retrieve certificate revocation lists when using a HTTP proxy. 18) A security issue in the Security Framework has been fixed where certain revoked certificates may be erroneously honored. 19) An error in the VPN server can be exploited by malicious, local users to execute commands with system privileges. 20) An error in WebKit can be exploited to execute arbitrary code via a specially crafted HTML document. 21) A weakness has been fixed in Installer where system privileges are used without explicit authorisation.
