MA-210.012010: MyCERT Alert - Latest Security Update for Multiple Apple Products Vulnerabilities (January 2010)

1.0 Introduction

Apple has recently released several security updates for Mac OS that cover several vulnerabilities such as:

1. CoreAudio

CVE-ID: CVE-2010-0036

Available for: Mac OS X v10.5.8, Mac OS X Server v10.5.8, Mac OS X v10.6.2, Mac OS X Server v10.6.2

Impact: Playing a maliciously crafted mp4 audio file may lead to an unexpected application termination or arbitrary code execution

Description: A buffer overflow exists in the handling of mp4 audio files. Playing a maliciously crafted mp4 audio file may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved bounds checking.

2. CUPS

CVE-ID: CVE-2009-3553

Available for: Mac OS X v10.5.8, Mac OS X Server v10.5.8, Mac OS X v10.6.2, Mac OS X Server v10.6.2

Impact: A remote attacker may cause an unexpected application termination of cupsd

Description: A use-after-free issue exists in cupsd. By issuing a maliciously crafted get-printer-jobs request, an attacker may cause a remote denial of service. This is mitigated through the automatic restart of cupsd after its termination. This issue is addressed through improved connection use tracking.

3. Flash Player plug-in

CVE-ID: CVE-2009-3794, CVE-2009-3796, CVE-2009-3797, CVE-2009-3798, CVE-2009-3799, CVE-2009-3800, CVE-2009-3951

Available for: Mac OS X v10.5.8, Mac OS X Server v10.5.8, Mac OS X v10.6.2, Mac OS X Server v10.6.2

Impact: Multiple vulnerabilities in Adobe Flash Player plug-in

Description: Multiple issues exist in the Adobe Flash Player plug-in, the most serious of which may lead to arbitrary code execution when viewing a maliciously crafted web site. The issues are addressed by updating the Flash Player plug-in to version 10.0.42. Further information is available via the Adobe web site at http://www.adobe.com/support/security/bulletins/apsb09-19.html

4. ImageIO

CVE-ID: CVE-2009-2285

Available for: Mac OS X v10.5.8, Mac OS X Server v10.5.8

Impact: Viewing a maliciously crafted TIFF image may lead to an unexpected application termination or arbitrary code execution

Description: A buffer underflow exists in ImageIO's handling of TIFF images. Viewing a maliciously crafted TIFF image may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved bounds checking. For Mac OS X v10.6 systems, this issue is addressed in Mac OS X v10.6.2.

5. Image RAW

CVE-ID: CVE-2010-0037

Available for: Mac OS X v10.5.8, Mac OS X Server v10.5.8, Mac OS X v10.6.2, Mac OS X Server v10.6.2

Impact: Viewing a maliciously crafted DNG image may lead to an unexpected application termination or arbitrary code execution

Description: A buffer overflow exists in Image RAW's handling of DNG images. Viewing a maliciously crafted DNG image may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved bounds checking.

6. OpenSSL

CVE-ID: CVE-2009-3555

Available for: Mac OS X v10.5.8, Mac OS X Server v10.5.8, Mac OS X v10.6.2, Mac OS X Server v10.6.2

Impact: An attacker with a privileged network position may capture data or change the operations performed in sessions protected by SSL

Description: A man-in-the-middle vulnerability exists in the SSL and TLS protocols. Further information is available at http://www.phonefactor.com/sslgap A change to the renegotiation protocol is underway within the IETF. This update disables renegotiation in OpenSSL as a preventive security measure. The issue does not affect services using Secure Transport as it does not support renegotiation.
