What is CVE-2015-5073?

A buffer overflow vulnerability exists in the find_fixedlength function of the PCRE library, affecting versions prior to 8.38.

Moreover, this vulnerability may enable attackers to bypass Address Space Layout Randomization (ASLR) protections, further compromising system integrity.
