Perl-Compatible Regular Expression (PCRE) library before 7.3 does not properly compute the length of (1) a \p sequence, (2) a \P sequence, or (3) a \P{x} sequence, which allows context-dependent attackers to cause a denial of service (infinite loop or crash) or execute arbitrary code.

Exploit prediction (EPSS)

5.07% probability of exploitation in the next 30 days, higher than 92% of all scored CVEs.
