Adobe Reader, Acrobat patch could be a month away

By
Adobe has confirmed the existence of a critical vulnerability in Adobe Reader and Adobe Acrobat, and plans to release an update by the middle of January 2010.

Reports of a new 0-day vulnerability in Adobe Acrobat and Adobe Reader surfaced in the last several days, and Adobe has now confirmed its existence.

Adobe has determined that the vulnerability can cause a crash and has the potential to allow an attacker to take control of the affected system. It appears that all versions of the programs are vulnerable, regardless of operating system.

The company says it plans to release patches for the two programs by January 12, 2010.

In the meantime, Adobe has described a mitigation technique that is more finely-grained than simply disabling JavaScript completely.

The JavaScript Blacklist Framework that's part of Acrobat and Reader can be used to prevent the use of the specific JavaScript function (Doc.Media.newPlayer) that is vulnerable.

Instructions for blacklisting this function are contained in an Adobe tech note.

Since full details of the vulnerability - including exploit code - are now publicly available, it seems sensible to follow Adobe's advice and either use the blacklist feature or disable JavaScript completely.

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.
