Package : libopenssl-ruby
Vulnerability : programming error
Problem type : local/remote
Debian-specific: no
CVE Id(s) : CVE-2007-5162 CVE-2007-5770

Several vulnerabilities have been discovered in Ruby, an object-oriented
scripting language. The Common Vulnerabilities and Exposures project
identifies the following problems:

CVE-2007-5162

It was discovered that the Ruby HTTP(S) module performs insufficient
validation of SSL certificates, which may lead to man-in-the-middle
attacks.

CVE-2007-5770

It was discovered that the Ruby modules for FTP, Telnet, IMAP, POP
and SMTP perform insufficient validation of SSL certificates, which
may lead to man-in-the-middle attacks.

The stable distribution (etch) no longer contains libopenssl-ruby.

For the old stable distribution (sarge), these problems have been fixed
in version 0.1.4a-1sarge1. Packages for sparc will be provided later.

We recommend that you upgrade your libopenssl-ruby packages.
