On Saturday, Adobe revealed that it would issue a patch for the latest Reader and Acrobat zero-day during the week of February 18, 2013, more precisely, sometime this week.
The issues affect Adobe Reader and Acrobat 11.0.01 and earlier for Windows and Macintosh, 10.1.5 and earlier for Windows and Macintosh, 9.5.3 and earlier 9.x versions for Windows and Macintosh, and Adobe Reader 9.5.3 and earlier 9.x versions for Linux.
The vulnerabilities are being exploited in the wild, so, until the patch is released, Adobe advises customers to enable Protected View
in their applications in order to protect themselves. Protected View can be enabled from the Edit > Preferences > Security menu.
Users are also advised to beware of suspicious-looking PDF files delivered via email since that’s how the issue is being exploited by cybercriminals.
