Several vulnerabilities have been discovered in Ruby, an object-oriented scripting language. The Common Vulnerabilities and Exposures project identifies the following problems:
It was discovered that the Ruby HTTP(S) module performs insufficient validation of SSL certificates, which may lead to man-in-the-middle attacks.
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 old stable distribution (sarge) these problems have been fixed in version 0.1.4a-1sarge1. Packages for sparc will be provided later.
The stable distribution (etch) no longer contains libopenssl-ruby.
We recommend that you upgrade your libopenssl-ruby packages.
MD5 checksums of the listed files are available in the original advisory.
