[v2.7] pcre: heap overflow vulnerability was found in pcre3, in find_fixedlenght() (CVE-2015-5073)
PCRE library is prone to a vulnerability which leads to Heap Overflow.
During subpattern calculation of a malformed regular expression, an
offset that is used as an array index is fully controlled and can be
large enough so that unexpected heap memory regions are accessed.
One could at least exploit this issue to read objects nearby of the
affected application’s memory.
Such information disclosure may also be used to bypass memory protection
method such as ASLR.
