Summary:	Ubuntu USN-900-1 (ruby1.9)
Description:	The remote host is missing an update to ruby1.9 announced via advisory USN-900-1. Details follow: Emmanouel Kellinis discovered that Ruby did not properly handle certain string operations. An attacker could exploit this issue and possibly execute arbitrary code with application privileges. (CVE-2009-4124) Giovanni Pellerano, Alessandro Tanasi, and Francesco Ongaro discovered that Ruby did not properly sanitize data written to log files. An attacker could insert specially-crafted data into log files which could affect certain terminal emulators and cause arbitrary files to be overwritten, or even possibly execute arbitrary commands. (CVE-2009-4492) It was discovered that Ruby did not properly handle string arguments that represent large numbers. An attacker could exploit this and cause a denial of service. This issue only affected Ubuntu 9.10. (CVE-2009-1904) Solution: The problem can be corrected by upgrading your system to the following package versions: Ubuntu 8.10: libruby1.9 1.9.0.2-7ubuntu1.3 ruby1.9 1.9.0.2-7ubuntu1.3 Ubuntu 9.04: libruby1.9 1.9.0.2-9ubuntu1.2 ruby1.9 1.9.0.2-9ubuntu1.2 Ubuntu 9.10: libruby1.9 1.9.0.5-1ubuntu1.2 ruby1.9 1.9.0.5-1ubuntu1.2 In general, a standard system upgrade is sufficient to effect the necessary changes. http://www.securityspace.com/smysecure/catid.html?in=USN-900-1 Risk factor : Critical
