Opera this week released a new version of the Web browser to correct at least two remotely exploitable security vulnerabilities. Separately, Microsoft said it plans to release eight updates on Tuesday as part of its regular monthly patch cycle. The latest version of Opera — 9.27 — is available at this link. More details on the vulnerabilities fixed are here and here. Microsoft said it most likely release eight updates, five of which will carry its most serious “critical” rating, meaning the vulnerabilities they fix can be exploited by attackers remotely with little or no help from the victim. As Microsoft’s individual updates often fixes multiple security holes, we could be talking about a large number of flaws patched tomorrow.
