"The regular expression library pcre was updated to 8.37 to fix three
security issues and a number of bugs and correctness issues.

The following vulnerabilities were fixed :

  - CVE-2015-2325: Specially crafted regular expressions
    could have caused a heap buffer overlow in
    compile_branch(), potentially allowing the execution of
    arbitrary code. (boo#924960)

  - CVE-2015-2326: Specially crafted regular expressions
    could have caused a heap buffer overlow in
    pcre_compile2(), potentially allowing the execution of
    arbitrary code. [boo#924961]

  - CVE-2014-8964: Specially crafted regular expression
    could have caused a denial of service (crash) or have
    other unspecified impact. [boo#906574]"
