|Gentoo Linux Security Advisory
Title: JRuby: Denial of Service (GLSA 201207-06)
Date: July 09, 2012
A hash collision vulnerability in JRuby allows remote attackers to
cause a Denial of Service condition.
JRuby is a Java-based Ruby interpreter implementation.
Vulnerable: < 188.8.131.52
Unaffected: >= 184.108.40.206
Architectures: All supported architectures
JRuby does not properly randomize hash functions to protect against hash
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-220.127.116.11"
