NVD Description
Note: Versions mentioned in the description apply only to the upstream pcre3 package and not the pcre3 package as distributed by Debian.
See How to fix? for Debian:10 relevant fixed versions and status.
The compile_branch function in PCRE before 8.37 allows context-dependent attackers to compile incorrect code, cause a denial of service (out-of-bounds heap read and crash), or possibly have other unspecified impact via a regular expression with a group containing a forward reference repeated a large number of times within a repeated outer group that has a zero minimum quantifier.
