CVE-2011-3102 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-3102):
  Off-by-one error in libxml2, as used in Google Chrome before 19.0.1084.46,
  allows remote attackers to cause a denial of service (out-of-bounds write)
  or possibly have unspecified other impact via unknown vectors.

[Comment 2 Alexandre Rostovtsev (RETIRED) 2012-05-21 02:25:22 UTC]

Fixed in libxml2-2.8.0_rc1 (the libxml2 upstream is finally on its way to making a new release)

Thanks. Just to make sure since this isn't a full release, are we moving to stabilize libxml2-2.8.0_rc1 now?

It would be my recommendation. The git changelog between 2.7.8 and 2.8.0-rc1 basically consists of fixes for various parser errors, crashes, infinite loops, memory leaks, and security holes; the only new features are support for lzma compression and <meta charset>.

Ok, thanks; then on we go. ;)
