TITLE

Apple Mac OS X CoreText embedded font vulnerability

DESCRIPTION

Use-after-free vulnerability in CoreText in Apple Mac OS X before 10.7.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted embedded font in a document. Successful exploits may allow attackers to execute arbitrary code in the context of the currently logged-in user; failed exploit attempts may cause denial-of-service conditions. The issue affects Mac OS X and Mac OS X Server versions prior to 10.7.3. NOTE: This issue was previously discussed in BID 51798 (Apple Mac OS X Prior to 10.7.3 Multiple Security Vulnerabilities) but has been given its own record to better document it. ---------------------------------------------------------------------- SC Magazine awards the Secunia CSI a 5-Star rating Top-level rating for ease of use, performance, documentation, support, and value for money.

This can be exploited to intercept CardDAV data. 2) An error in the bundled version of Apache can be exploited to cause a temporary DoS (Denial of Service). For more information: SA46013 3) A design error in Apache within the Secure Sockets Layer 3.0 (SSL) and Transport Layer Security 1.0 (TLS) protocols when using a block cipher in CBC mode can be exploited to decrypt data protected by SSL. 4) An error in ATS when handling data-font files can be exploited to corrupt memory via a specially crafted font opened by Font Book. 5) An error in CFNetwork when handling URLs can be exploited to disclose sensitive information via a specially crafted web page as a request could be sent to an incorrect origin server. 6) An error in CFNetwork when handling URLs can be exploited to disclose sensitive information via a specially crafted web page as unexpected request headers could be sent. 7) An integer overflow error in ColorSync when handling images with embedded ColorSync profiles can be exploited to cause a heap-based buffer overflow via a specially crafted image. 8) An error in CoreAudio when handling AAC encoded audio streams can be exploited to cause a buffer overflow when playing specially crafted audio content. 9) An error in CoreMedia when handling H.264 encoded movies can be exploited to cause a heap-based buffer overflow. 10) A use-after-free error in CoreText when handling documents containing fonts can be exploited to dereference already freed memory via a specially crafted font. 11) An error exists in CoreUI when handling long URLs and can be exploited via a specially crafted website. 12) An error in curl can be exploited by remote servers to impersonate clients via GSSAPI requests. For more information: SA45067 13) Two of the certificate authorities in the list of trusted root certificates have issued intermediate certificates to DigiCert Malaysia, who has issued certificates with weak keys that cannot be revoked. 14) A design error in dovecot within the Secure Sockets Layer 3.0 (SSL) and Transport Layer Security 1.0 (TLS) protocols when using a block cipher in CBC mode can be exploited to decrypt data protected by SSL. 15) An error in the uncompress command line tool when decompressing compressed files can be exploited to cause a buffer overflow. For more information: SA45544 16) An error in ImageIO when parsing TIFF images can be exploited to cause a buffer overflow. For more information see vulnerability #9: SA45325 17) An error in ImageIO when handling ThunderScan encoded TIFF images can be exploited to cause a buffer overflow. For more information see vulnerability #2: SA43593: 18) An error exists in the bundled version of libpng. For more information: SA46148 19) An error in Internet Sharing may cause the used Wi-Fi configuration to revert to factory defaults (e.g. disabling the WEP password) after a system update. 20) An error in Libinfo can be exploited to disclose sensitive information via a specially crafted website. For more information see vulnerability #4: SA46747 21) An integer overflow error in libresolv when parsing DNS resource records can be exploited to cause a heap-based buffer overflow. 22) An error in libsecurity may cause some EV certificates to be trusted even when the corresponding root is marked untrusted. 23) Multiple errors in OpenGL when handling GLSL compilation can be exploited to corrupt memory. 24) Multiple errors exist in the bundled version of PHP. For more information: SA44874 SA45678 25) Various errors in FreeType when handling Type 1 fonts can be exploited to corrupt memory. For more information: SA46575 26) An error in QuickTime when parsing MP4 encoded files can be exploited to access uninitialised memory. 27) A signedness error in QuickTime when handling font tables embedded in movie files can be exploited to corrupt memory. 28) An off-by-one error in QuickTime when handling rdrf atoms in movie files can be exploited to cause a single byte buffer overflow. 29) An error in QuickTime when parsing JPEG2000 images can be exploited to cause a buffer overflow. 30) An error in QuickTime when parsing PNG images can be exploited to cause a buffer overflow. 31) An error in QuickTime when handling FLC encoded movie files can be exploited to cause a buffer overflow. 32) Multiple errors exists in the bundled version of SquirrelMail. For more information: SA40307 SA45197 33) Various errors exist in the bundled version of Subversion. For more information: SA44681 34) Time Machine does not verify that a designated remote AFP volume or Time Capsule is used for subsequent backups. This can be exploited to access backups by spoofing the remote volume. 35) Errors exist in the bundled version of Tomcat. For more information: SA44981 36) An error in WebDAV Sharing when handling user authentication can be exploited by local users to gain escalated privileges. 37) An error exists in the bundled version of Webmail. For more information: SA45605 SOLUTION: Update to OS X Lion version 10.7.3 or apply Security Update 2012-001.
