Key: JRUBY-5502 URL: http://jira.codehaus.org/browse/JRUBY-5502 Project: JRuby Issue Type: Bug Components: Extensions Affects Versions: JRuby 1.6RC2, JRuby 1.6RC1, JRuby 1.5.6 Reporter: Wayne Meissner Assignee: Wayne Meissner Priority: Blocker Fix For: JRuby 1.6RC3 org.jruby.ext.socket.RubyUnixSocket#recvfrom() allocates a fixed size native buffer of 1024 bytes, but then proceeds to read however many bytes the caller requested into that buffer. so, a call of e.g. recvfrom(2048) could overflow the temporary buffer and crash the VM. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email
