Debian Security Advisory DSA-3322-1 security@debian.org

– ————————————————————————-

Package : ruby-rack
CVE ID : CVE-2015-3225
Debian Bug : 789311

Tomek Rabczak from the NCC Group discovered a flaw in the
normalize_params() method in Rack, a modular Ruby webserver interface.
A remote attacker can use this flaw via specially crafted requests to
cause a `SystemStackError` and potentially cause a denial of service
condition for the service.

For the oldstable distribution (wheezy), this problem has been fixed
in version 1.4.1-2.1+deb7u1.

For the stable distribution (jessie), this problem has been fixed in
version 1.5.2-3+deb8u1.

For the unstable distribution (sid), this problem has been fixed in
version 1.5.2-4.

We recommend that you upgrade your ruby-rack packages.
