Jeff Rivett has worked with and written about computers since the early 1980s. His first computer was an Apple II+, built by his father and heavily customized. Jeff's writing appeared in Computist Magazine in the 1980s, and he created and sold a game utility (Ultimaker 2, reviewed in the December 1983 Washington Apple Pi Journal) to international markets during the same period. Proceeds from writing, software sales, and contract programming gigs paid his way through university, earning him a Bachelor of Science (Computer Science) degree at UWO. Jeff went on to work as a programmer, sysadmin, and manager in various industries. There's more on the About page, and on the Jeff Rivett Consulting site.

Firefox 25.0.1 released

Another stealth release of Firefox happened on November 15. Version 25.0.1 apparently fixes some security vulnerabilities and other bugs. With the total lack of any kind of announcement for this release, and the way the release notes include changes in previous releases, it’s difficult to be certain what’s new in this version. For instance, the version 25.0.1 release notes point to the ‘Known vulnerabilities‘ page, but there’s nothing listed there that’s specific to version 25.0.1. The release notes for 25.0.1 also point to Bugzilla (‘complete list of changes‘), but the list of fixed bugs shows everything for version 25, and nothing specific to version 25.0.1. What a mess.

Update 2013Nov23: EWeek has more information about the security vulnerabilities fixed in Firefox 25.0.1 (even if Mozilla doesn’t).

Patch Tuesday for November 2013

It’s the second Tuesday of November, which means it’s time to update all your Windows computers. This month’s announcement lists eight bulletins, affecting Windows, Office, and Internet Explorer.

A patch for the recently-reported vulnerability in Internet Explorer will also be made available later today, according to Microsoft. It will appear in the November 2013 Patch Tuesday announcement as bulletin #3 (MS13-090).

For the full technical details on this month’s updates, see the related post on the Microsoft Security Response Center blog.

New Internet Explorer vulnerability being actively exploited

Another new exploit has been discovered by security researchers, this one affecting Internet Explorer. The exploit uses two as-yet unpatched vulnerabilities in IE 7 through 10.

This is not to be confused with the recently-announced exploit affecting Microsoft Office.

Recommendations:

  • Avoid using Internet Explorer. If that’s not practicable, exercise extreme caution when browsing the web.
  • Install and use Microsoft’s Enhanced Mitigation Experience Toolkit (EMET)

Ars Technica has more details.

Update 2013Nov12: a patch for this vulnerability will be included with this month’s Patch Tuesday updates, later today.
