Description Tim Sammut (RETIRED) gentoo-dev 2011-05-28 18:14:31 UTC
From $URL:

        * A bug was found in the pcre implementation for subst(). If the
          "global" flag is specified and pcre returns an error, an infinite
          loop is created, consuming memory in the process. It is triggered
          by PCRE 8.12, but could potentially affect older versions too.

Michael, 3.2.4 is already in the tree. Is it suitable for stabilization?

CVE-2011-1951 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1951):
  lib/logmatcher.c in Balabit syslog-ng before 3.2.4, when the global flag is
  set and when using PCRE 8.12 and possibly other versions, allows remote
  attackers to cause a denial of service (memory consumption) via a message
  that does not match a regular expression.
Comment 7 Mr. Bones. (RETIRED) gentoo-dev 2013-05-10 22:42:16 UTC
what's the next step in getting this closed?

Releasing a GLSA. 

Please read the note at the bottom of bugzilla about NOT closing security bugs.
Comment 9 Mr. Bones. (RETIRED) gentoo-dev 2014-11-09 17:29:49 UTC
Then get it done.  Three years makes a GLSA irrelevant.
