Mozilla on Wednesday released an update to its popular Firefox Web browser that fixes a dozen vulnerabilities, seven of which it deems "critical."
The most serious of the flaws could be exploited by cyberattackers to commandeer a vulnerable PC, according to Mozilla. The company, which oversees Firefox development, has published security advisories for each of the flaws repaired by the Firefox update.
The flaws are fixed in Firefox 1.5.0.5, which Mozilla has started pushing out to Firefox users via the update feature in the open-source Web browser. In addition to the security fixes, the browser update includes stability improvements, as well as changes for the Frisian version for some users in the Netherlands, Mozilla said.
"Firefox 1.5.0.5 is a security update that is part of our ongoing program to provide a safe Internet experience for our customers," Mozilla said on its Web site. "We recommend that all users upgrade to this latest version."
Security monitoring company Secunia rates the update as "highly critical," one notch below its most serious ranking.
