Adobe update – excessive traffic to ardownload.adobe.com
Dec 16th
Adobe has not been without its problems of late, and whilst there have been security issues that could have lead to losses, so far none of our clients have suffered financially from Adobe’s failings. Until now that is.
One of our Clients had their ADSL cut off this week as they had exceeded the usage policy. Why? Adobe Update Manager on one Windows XP PC had decided to download over 70GB of data over the course of a 7 day period. It would appear that it was getting itself in a loop and just kept trying to update continuously, 70GB worth of continuously.
The Adobe website serves the update MSI binary files as content type Text/Plain, the Adobe Update client has a very short timeout and immediately opens another connection to re-start the download. Hence if there is a slow connection or the caching server does not return the whole file in a timely manner the Adobe Update client enters the infinite loop of retries, causing the excessive bandwidth consumption witnessed here.
There are several forum threads including on Adobe’s own site http://forums.adobe.com/thread/392129 all linking this issue to a conflict between and old version of WebMarshall and Adobe updater; however our machines do not use WebMarshall and we do not have it installed anywhere on our networks.
We do however use Squid caching on our CentOS 5 servers. The server in this instance seems to be fulfilling the requests on each occasion in a timely manner – the issue is that each time Adobe updater passes a URL it is different in key areas, which Squid interprets as a separate request. This is not abnormal and we have seen this before when we have tried to configure squid to cache Windows updates. However rather than enter a loop of requests, Windows updates simply fail. Other automatic updaters work well with caching systems and indeed most ISPs are now implementing different forms of web caching on their own networks. Dose this mean the Adobe issue is affecting them in the same way?
The issue seems to only affect PCs (or at least we have seen no affected Mac users as yet), and it also seems to affect most Adobe products.
For now Adobe and the ISPs have remained quiet on the issue, however we have 3 other clients (and my own home ADSL ) who cannot update Adobe at all, access to ardownload.adobe.com appears to have been blocked by the ISP. Quite when the Adobe update issue will be resolved is unknown; however we have also taken the decision to block access to ardownload.adobe.com from all of our networks, for the moment.
Richard, one of our Systems Admin Team has published a more detailed account of the technicalities involved here: http://richard.blog.kraya.co.uk/2009/12/16/a-big-adobe-problem/
Security Bulletin – Adobe Reader and Acrobat
May 14th
Below is an update to Security Bulletin – Adobe – April 09
Adobe have published a new Security Bulletin and provided updates for Adobe Reader and Acrobat patches. These updates resolve the previously reported vulnerabilities in Adobe Reader 9.1 and Acrobat 9.1 and earlier versions. This vulnerability (CVE-2009-1492) would cause the application to crash and could potentially allow an attacker to take control of the affected system remotely and install Malicious code.
We have already recommended that user consider using alternatives to Adobe reader, this continues to be our current advice. However users still using Adobe should now update and install these patches as soon as practical.
Adobe recommends users of Adobe Reader 9.1 and Acrobat 9.1 and earlier versions update to Adobe Reader 9.1.1 and Acrobat 9.1.1. Adobe recommends users of Acrobat 8 update to Acrobat 8.1.5, and users of Acrobat 7 update to Acrobat 7.1.2. For Adobe Reader users who can’t update to Adobe Reader 9.1.1, Adobe has provided the Adobe Reader 8.1.5 and Adobe Reader 7.1.2 updates.
