A hash collision vulnerability in JRuby allows remote attackers to cause a Denial of Service condition.
|Package||dev-java/jruby on all architectures|
|Affected versions||< 184.108.40.206|
|Unaffected versions||>= 220.127.116.11|
JRuby is a Java-based Ruby interpreter implementation.
JRuby does not properly randomize hash functions to protect against hash collision attacks.
A remote attacker could send a specially crafted input, possibly resulting in a Denial of Service condition.
There is no known workaround at this time.
All JRuby users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-java/jruby-18.104.22.168"
