Test ID:1.3.6.1.4.1.25623.1.0.66843
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-900-1 (ruby1.9)
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.
