Debian Security Advisory

DSA-1139-1 ruby1.6 -- missing privilege checks

Date Reported:
03 Aug 2006
Affected Packages:
ruby1.6
Vulnerable:
Yes
Security database references:
In the Debian bugtracking system: Bug 378029.
In Mitre's CVE dictionary: CVE-2006-3694.
More information:

It was discovered that the interpreter for the Ruby language does not properly maintain "safe levels" for aliasing, directory accesses and regular expressions, which might lead to a bypass of security restrictions.

For the stable distribution (sarge) this problem has been fixed in version 1.6.8-12sarge2.

The unstable distribution (sid) does no longer contain ruby1.6 packages.

We recommend that you upgrade your Ruby packages.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
