TOP VULNERABILITY THIS WEEK: WebKit bug affects Safari, Chrome users

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Apple WebKit opens users up to malicious advertising
Description: Multiple vulnerabilities in Apple’s WebKit are allowing attackers to serve users’ malicious advertisements. This campaign affected the Google Chrome and Safari web browsers on iOS and MacOS, but the vulnerabilities were all patched out in Apple’s latest series of security updates. All the ads centered around the user’s specific mobile carrier, hoping to entice them to visit malicious websites. The vulnerabilities would allow the ads to break out of any sandboxes in place.

Title: Remote code execution bug in vBulletin
Description: A now-patched vulnerability in the popular service vBulletin is allowing attackers to completely take over sites that use the software. vBulletin powers the commenting functions for many popular sites. An attacker could exploit this vulnerability to gain the ability to remotely execute malicious code on any vBulletin server running versions 5.0.0 through 5.5.4. This bug was initially dropped as a zero-day by an anonymous user, but has since been patched by the company. The Snort rules below prevent any attempt to inject code into the server using this bug. Marcos Rodriguez wrote these rules.
