You are being emailed as the upstream contact. Please keep oss-security CC'd for any updates on this issue. This issue should be considered public, but has not yet been assigned a CVE. Once a CVE is assigned, please mention it in any changelogs. Details from the public bug follow: https://launchpad.net/bugs/777804 From the reporter: ---- I am reporting a persistent xss vector in gitweb, note this requires a user to have commit access to a repository that gitweb is configured to display. The vector is the fact that gitweb "serves" up xml files - which can (just as gitweb does) embed html that could be used to perform a cross-site scripting attack. e.g. (lol.xml). <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US" lang="en-US"> <head> </head> <script>alert(1);</script> </html> and viewed at http://$HOSTNAME/$PATH_TO_GITWEB/?p=lolok;a=blob_plain;f=lol.xml ---- Thanks in advance for your cooperation in coordinating a fix for this issue, Jamie Strandboge  oss-security@...ts.openwall.com is a public mailing list for people to collaborate on security vulnerabilities and coordinate security updates. -- Jamie Strandboge | http://www.canonical.com Download attachment "signature.asc" of type "application/pgp-signature" (837 bytes)
