Several messages should be escaped in ticketlog.js

[Jun Omae]

I found XSS vulnerabilities in ticketlog.js.

• result.msg_query_err in tracticketchangelogplugin/0.12/ticketlog/htdocs/ticketlog.js@14183:8#L5​
• result.msg_tkt_rev_head in tracticketchangelogplugin/0.12/ticketlog/htdocs/ticketlog.js@14183:25#L21​
• revision.author and revision.message in tracticketchangelogplugin/0.12/ticketlog/htdocs/ticketlog.js@14183:43,44#L39​

I'll post patch for that.

Thanks. Please feel free to push changes for this plugin at any time. I made a few attempts to get in touch with richard through tickets some time ago, and then pushed ahead with making changes when there was no reply.

I just created patch, t11999.diff​. I'll commit it later.

Also, I think we should use display_rev() rather than normalize_rev() because raw revision (40 bytes) will be displayed if git and mercurial.

Both patches look good. Should revision.message be escaped on line 52 of the patch?

[Jun Omae]

I misunderstood about that. revision.message shouldn't be escaped. Output of format_to_oneliner() is stored on it at tracticketchangelogplugin/0.12/ticketlog/web_ui.py@14192:204#L190​.
