Title: JRuby: Denial of Service (GLSA 201207-06)
Severity: normal
Exploitable: remote
Date: July 09, 2012
Bug(s): #396305
ID: 201207-06
Synopsis
A hash collision vulnerability in JRuby allows remote attackers to
cause a Denial of Service condition.
Background
JRuby is a Java-based Ruby interpreter implementation.
Affected Packages
Package: dev-java/jruby
Vulnerable: < 1.6.5.1
Unaffected: >= 1.6.5.1
Architectures: All supported architectures
Description
JRuby does not properly randomize hash functions to protect against hash
collision attacks.
Impact
A remote attacker could send a specially crafted input, possibly
resulting in a Denial of Service condition.
Workaround
There is no known workaround at this time.
Resolution
All JRuby users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/jruby-1.6.5.1"
|
