In a notice posted on its Web site last Friday, the Raleigh, N.C.-based open source vendor posted links to 12 security advisories, which that deal with 47 vulnerabilities. Three are rated "critical." Five are rated "important." All of them affect Red Hat's open source operating system.
Another "critical" vulnerability update involves security issues in Ekiga packages. Ekiga is a tool used to communicate with video and audio over the Internet. Format string flaws were found in the way Ekiga processes certain messages. If a user is running Ekiga, a remote attacker who can connect to Ekiga could trigger the flaw and potentially execute arbitrary code with the user's privileges, according to the advisory.
Red Hat is recommending that users update their software as soon as possible.
