pcre3 - arbitrary code execution

Tavis Ormandy discovered that PCRE, the Perl-Compatible Regular
Expression library, may encounter a heap overflow condition when
compiling certain regular expressions involving in-pattern options and
branches, potentially leading to arbitrary code execution.

For the stable distribution (etch), this problem has been fixed in
version 6.7+7.4-4.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your pcre3 packages.
