Title:
  Stack Corruption in PCRE 8.35

Status in pcre3 package in Ubuntu:
  Triaged

Bug description:
  Various security issues have been fixed in PCRE since 8.35.  Here is
  an example of using a malicious pattern within the Ubuntu PHP5 package
  that leads to stack corruption:

  php5 -r 'preg_match("/(?(1)(()(?1)1)+)/","abcdef", $matches,
  PREG_OFFSET_CAPTURE);'

  Loading
  ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.38.tar.gz
  with the upgrade-pcre.php script resolves this issue.
