SecurityVulns ID:13370
Threat Level:
Description:DoS, code execution.
Affected:RUBY : rack 1.5
CVE:CVE-2013-0263 (Rack::Session::Cookie in Rack 1.5.x before 1.5.2, 1.4.x before 1.4.5, 1.3.x before 1.3.10, 1.2.x before 1.2.8, and 1.1.x before 1.1.6 allows remote attackers to guess the session cookie, gain privileges, and execute arbitrary code via a timing attack involving am HMAC comparison function that does not run in constant time.)
 CVE-2013-0184 (Unspecified vulnerability in Rack::Auth::AbstractRequest in Rack 1.1.x before 1.1.5, 1.2.x before 1.2.7, 1.3.x before 1.3.9, and 1.4.x before 1.4.4 allows remote attackers to cause a denial of service via unknown vectors related to "symbolized arbitrary strings.")
 CVE-2013-0183 (multipart/parser.rb in Rack 1.3.x before 1.3.8 and 1.4.x before 1.4.3 allows remote attackers to cause a denial of service (memory consumption and out-of-memory error) via a long string in a Multipart HTTP packet.)
 CVE-2011-5036 (Rack before 1.1.3, 1.2.x before 1.2.5, and 1.3.x before 1.3.6 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.)
