Update available for privilege escalation issue in Bridge 1.0.3 installer package

Release date: April 10, 2007

Vulnerability identifier: APSB07-09

CVE number: CVE-2007-1279

Platform: Macintosh

Affected software versions: Bridge 1.0.3 update

Summary

There is a problem with the previous installer for Bridge update 1.0.3.  A potential vulnerability occurs when the administrator attempts to install the patch. While the patch is being installed a local non-administrative user may be able to gain administrative privileges. 

Solution

For customers who are not planning to distribute Bridge 1.0.3 via desktop management tools like Apple Remote Desktop or have previously updated to Bridge 1.0.3 or Bridge 1.0.4, no action is necessary. Versions of the Bridge updater available on adobe.com have been corrected.  If customers have previously downloaded a copy of the updater, it should be replaced with the version here.

Please use the following instructions to confirm the SHA-1 digest of the latest version of the Bridge 1.0.3 update file:

  1. Open Terminal.
  2. Type the following: /usr/bin/openssl.
  3. Press return.
  4. Type: sha1 [full path to Bridge update .dmg file] (note: drag the file from Finder directly into the terminal window to display the path).
  5. The SHA-1 digest is displayed as: sha1 ([full path to the file])= [checksum amount].
  6. Confirm that the checksum matches that of the new Bridge 1.0.3 .dmg file: 594038b0af7bc57ef24d0a2a9483d4eaaef399da.
  7. If necessary, download the new update file from here.

NOTE: If customers have not already done so, Adobe recommends updating to Bridge 1.0.4 after applying the 1.0.3 update.

Severity rating

Adobe categorizes this as a moderate issue and recommends users use the updated installer.

Details
