Debian: DSA-1412-1 Critical: Ruby SSL Certificate Validation Issue

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.

For the stable distribution (etch), these problems have been fixed in
version 1.9.0+20060609-1etch1. Updated packages for hppa and sparc will
be provided later.

The old stable distribution (sarge) doesn't contain ruby1.9 packages.

We recommend that you upgrade your ruby1.9 packages.
